Answer:

  x = -7/9

Step-by-step explanation:

The usual recommendation is to clear fractions first. Here, you can do that by multiplying both sides of the equation by 6.

  6(-1/2(3x -4) +3x) = 6(5/6)

  -9x +12 +18x = 5 . . . . . . . . . simplify

  9x = -7 . . . . . . . . . . . . . . . . . subtract 12

  x = -7/9 . . . . . .divide by 9

__

Another way to do this is to eliminate parentheses first.

  -3/2x +2 +3x = 5/6

  3/2x = -7/6 . . . . . . . . . collect terms, subtract 2

  x = (-7/6)(2/3) = -7/9 . . . . multiply by 2/3

The linear inequality of the graph is: -x + 2y + 1 > 0

First, we calculate the slope of the dashed line using:

\(m = \frac{y_2 - y_1}{x_2 - x_1}\)

Two points on the graph are:

(1, 0) and (3, 1)

The slope (m) is:

\(m = \frac{1 - 0}{3 - 1}\)

This gives

m = 0.5

The equation of the line is calculated as:

\(y = m(x -x_1) + y_1\)

So, we have;

\(y = 0.5(x -1) + 0\)

This gives

\(y = 0.5x -0.5\)

Multiply through by 2

\(2y = x - 1\)

Now, we convert the equation to an inequality.

The line on the graph is a dashed line. This means that the inequality is either > or <.

Also, the upper region of the graph that is shaded means that the inequality  is >.

So, the equation becomes

2y > x - 1

Rewrite as:

-x + 2y + 1 > 0

So, the linear inequality is: -x + 2y + 1 > 0

Find a linear inequality with the following solution set. Each grid line represents one unit. (Give your answer in the form ax+by+c>0 or ax+by+c \(\geq\) 0 where a, b, and c are integers with no common factor greater than 1.)

Answer & Step-by-step explanation:

To multiply these two binomials, we can use the distributive property as follows:

(2x+5)(3x+1) = 2x(3x+1) + 5(3x+1)

Now, we can simplify each term:

2x(3x+1) = 6x^2 + 2x

5(3x+1) = 15x + 5

Putting these back together, we get:

(2x+5)(3x+1) = 6x^2 + 2x + 15x + 5

Simplifying the middle two terms, we get:

(2x+5)(3x+1) = 6x^2 + 17x + 5

Therefore, the expression that is equivalent to (2x+5)(3x+1) is 6x^2 + 17x + 5.

If a categorical variable that can take the values from the set {Red, Blue, Green, Yellow} is included as an independent variable in a linear regression, the number of dummy variables that are created is two

When a categorical variable that has n categories is to be included as an independent variable in a linear regression analysis, it must be converted to n - 1 dummy variables. The reason for this is that including all n categories as dummy variables would cause perfect multicollinearity in the regression analysis, making it impossible to estimate the effect of each variable.In this case, the set of categories {Red, Blue, Green, Yellow} has four categories. As a result, n - 1 = 3 dummy variables are required to represent this variable in a linear regression. This is true since each category is exclusive of the others, and we cannot assume that there is an inherent order to the categories.The dummy variable for the first category is included in the regression model by default, and the remaining n - 1 categories are represented by n - 1 dummy variables. As a result, the number of dummy variables that are required to represent the categorical variable in the regression model is n - 1.

Thus, if a categorical variable that can take the values from the set {Red, Blue, Green, Yellow} is included as an independent variable in a linear regression, the number of dummy variables that are created is two .

Answer:

The number of black pieces needed to manufacture the ball is 11 black pieces

Step-by-step explanation:

Given that the number of pieces in the soccer ball = 32 pieces

The shape of the white piece = Hexagon

The shape of the black piece = Pentagon

Each black piece borders with only white pieces

Each white piece borders with three black pieces and three white pieces

For the first black pie  piece is borders to 5 white pieces total 6 pieces

Each of the five white pieced borders 3 pieced total 5 black pieces on the sides and one white piece on top to make an additional 10 piece total = 10 + 6 = 21 piece

Each black piece holds one white piece to add extra 5 pieces to make the total = 26

At the outermost shell of the arrangement, each of the white piece attached  to a black piece will attach to an extra black piece, bringing the total to 26 + 5 = 31,

The last piece is white

Total black piece = 1 + 5 + 5 = 11 black pieces.

To draw the supply and demand for labor in a market in equilibrium, and illustrate the impact of a labor union, we can use a standard supply and demand graph with quantity of labor (Q) on the x-axis and wage (W) on the y-axis.

Market in Equilibrium:

In a competitive labor market, the supply of labor represents the quantity of workers willing and able to work at various wage levels. The demand for labor represents the quantity of workers that firms are willing to hire at various wage levels. In equilibrium, the supply and demand curves intersect.

Let's assume that at the equilibrium, the wage is labeled as We and the quantity of labor is labeled as Qe.

Graphically, the supply curve (S) slopes upward from left to right, indicating that higher wages incentivize more workers to enter the labor market. The demand curve (D) slopes downward from left to right, indicating that higher wages result in fewer workers being demanded by firms.

Place the equilibrium point (We, Qe) where the supply and demand curves intersect on the graph.

Impact of a Labor Union:

When a labor union represents workers in the industry, it can negotiate for better wages and working conditions on behalf of its members. This can shift the supply and/or demand curve.

a. Shift in the Supply Curve:

If the labor union successfully negotiates higher wages for its members, it can result in an upward shift of the supply curve. This shift represents an increase in the quantity of labor supplied at each wage level.

Draw a new supply curve (S') above the original supply curve. The new supply curve should intersect the demand curve (D) at a higher wage level (Wu) and a greater quantity of labor (Qu).

b. Shift in the Demand Curve:

If the labor union's demands result in higher production costs for firms, it can lead to a decrease in labor demand. This can cause a leftward shift of the demand curve.

Draw a new demand curve (D') to the left of the original demand curve. The new demand curve should intersect the supply curve (S) at a lower wage level (Wd) and a lower quantity of labor (Qd).

Label the new equilibrium point with a labor union as (Wu, Qu).

Note: The specific shift and its impact (supply or demand) depend on various factors and the specific circumstances of the labor union's actions. The above explanation provides a general example.

By graphically illustrating the changes in the labor market due to the presence of a labor union, you can visually see the impact on the equilibrium wage and quantity of labor.

The equation of the line in slope-intercept form representing the amount of money in Marus's account over time is y = mx + b.

In the slope-intercept form of a linear equation, y represents the dependent variable (in this case, the amount of money in Marus's account), x represents the independent variable (time), m represents the slope of the line, and b represents the y-intercept (the value of y when x = 0).

To determine the equation of the line, we need to know the slope and y-intercept values. The slope, m, represents the rate of change of Marus's account balance over time. If we have two points on the line, we can calculate the slope using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Once we have the slope, we can substitute it along with the coordinates of any point on the line into the slope-intercept form equation y = mx + b to solve for the y-intercept, b. The y-intercept is the value of y when x = 0, meaning it represents the initial amount of money in Marus's account.

By determining the values of m and b, we can write the equation of the line in slope-intercept form and have a mathematical representation of how the amount of money in Marus's account changes over time.

Answer:

Therefore Jet Skis cost $50 for the rental and Kayaks cost $20.

Step-by-step explanation:

Since they both rent the vehicles at the same price, "x" for jet skis and "y" for kayaks", we can create equations for each store and a system of equations for these, as shown below:

Watersports:

12*x + 9*y = 780

Fun Rentals:

7*x + 11*y = 570

System:

\(\left \{ {{12*x + 9*y=780} \atop {7*x + 11*y=570}} \right.\)

We can isolate "x" on the first equation:

\(x = \frac{780 - 9*y}{12}\)

And use it on the second:

\(7*[\frac{780 - 9*y}{12}] + 11*y = 570\\5460 -63*y = 6840 - 132*y\\132*y - 63*y = 6840 - 5460\\69*y = 1380\\y = 20\\\)

We can now use this value to find "x":

\(x = \frac{780 - 9*20}{12} = 50\)

Therefore Jet Skis cost $50 for the rental and Kayaks cost $20.

Step-by-step explanation:

The piecewise function \(C_{B}(t)\) captures the total cost of Plan B per month based on the number of minutes used, considering the fixed monthly cost and the additional cost for exceeding the initial 200 minutes.

The piecewise function CB(t) that determines the total cost CB of Plan B per month in dollars using t minutes can be written as follows:

CB(t) = $60 + 0.2(t - 200), if t > 200,

CB(t) = $60, if t ≤ 200.

In this function, the fixed monthly cost of Plan B is represented by $60. For minutes beyond the initial 200 minutes, the additional cost is calculated by multiplying the excess minutes (t - 200) by the per-minute rate of $0.2. This additional cost is then added to the fixed monthly cost of $60.

For example, if a customer uses 250 minutes in a month, the total cost CB(t) for Plan B would be:

CB(250) = $60 + 0.2(250 - 200) = $60 + 0.2(50) = $60 + $10 = $70.

If the customer uses 180 minutes in a month, the total cost CB(t) for Plan B would be:

CB(180) = $60 (since 180 ≤ 200).

Therefore, the piecewise function CB(t) captures the total cost of Plan B per month based on the number of minutes used, considering the fixed monthly cost and the additional cost for exceeding the initial 200 minutes.

Based on the above, the segments that are perpendicular to EF are LM and NP.

Note that when two lines are perpendicular, we can say that;

M1 * M2 = -1 As M1 and M2 are known to be the slopes of the lines.

Therefore, when the the slope of EF is said to be −5/2, then  one can say that the slope of  the segment that is said to be  perpendicular to EF will have to be equal to m1*m2=-1, m2=-1/m1, m2=-1/(-5/2) or m2=2/5.

Scenario one:

JK , if J is at (3, −2) and K is at (5, −7)

To find the slope JK, then

m=(y2-y1)/x2-x1)

m=(-7+2)/(5-3)

m=-5/2

-5/2 is not equal to 2/5

Therefore,  JK is not perpendicular to EF

Scenario 2

Find GH , when G is at (6, 7) and H is at (4, 12)

To find the slope GH

m=(y2-y1)/x2-x1)

m=(12-7)/(4-6)

m=5/-2

m=-5/2

Since -5/2 is not equal to 2/5 then GH is not perpendicular to EF

Scenario 3:

Find LM , If L is at (1, 9) and M is at (6, 11)

To find the slope LM, then

m=(y2-y1)/x2-x1)

m=(11-9)/(6-1)

m=2/5

Since 2/5 is equal to 2/5

Then LM is perpendicular to EF

Scenario 4:

Find NP , if N is at (−3, 4) and P is at (−8, 2)

To find the slope NP, then

m=(y2-y1)/x2-x1)

m=(2-4)/(-8+3)

m=-2/-5

m=2/5

Since 2/5 is equal to 2/5.

Therefore,  NP is perpendicular to EF

When adding or subtracting numbers with significant figures, the result should be rounded to the least precise decimal place of the measurements involved.

When performing addition or subtraction operations with numbers that have different levels of precision, it is important to ensure that the result is reported with the appropriate number of significant figures.

The rule states that the result should be rounded to the least precise decimal place among the measurements involved in the calculation.

For example, consider the addition of 53.5 and 46.5. Both numbers have one decimal place, so the sum should also be reported with one decimal place.

Adding the numbers gives us 100, but when applying the rule, we round the result to 100.0 to reflect the precision of the original measurements.

Similarly, if we subtracted 46.5 from 53.5, the result would still have one decimal place: 7.0.

Step-by-step explanation:

First, let's find how much water will drip in an hour (60 minutes), so we can make an equation:

8/12 = x/60

And if you multiply both sides of the equation by 60 you will get 8*5 = x which is 40. So, we know that in one hour, 40 ounces of water will drip from the bathroom faucet. To find how much water will drip in a day, just multiply 40 by 24 (since there are 24 hours in a day). That would result in 960.
