Step-by-step explanation:

The letters corresponding to the solutions are: x = 10, x = -3/2, x = -1/9, x = -6, x = 10/3 That gives you the letters "joke"1.  5x – 7 = 4x + 3.

To solve for x, we can add 7 to both sides of the equation and subtract 4x from both sides:

5x - 7 + 7 = 4x + 3 + 7

5x = 4x + 10

x = 10

2.  6 + 2x = 7x - 9

To solve for x, we can add 9 to both sides of the equation, subtract 6 from both sides and divide both sides by -1:

6 + 2x + 9 = 7x - 9 + 9

2x = -3

x = -3/2

3. 8x + 1 = -8 - x

To solve for x, we can add x to both sides of the equation and add 8 to both sides:

8x + 1 + x = -8 - x + x + 8

9x + 1 = 0

x = -1/9

4. -5 + 12x = 18x + 7

To solve for x, we can subtract 12x from both sides of the equation and add 5 to both sides:

-5 + 12x - 12x = 18x + 7 - 12x

-5 = 6x + 7

x = -6

5.  -4x + 3 = 5x - 13 - x

To solve for x, we can add x to both sides of the equation, subtract 3 from both sides and divide both sides by -1:

-4x + 3 + x = 5x - 13 - x + x + 3

-3x = -10

x = 10/3

The letters corresponding to the solutions are: x = 10, x = -3/2, x = -1/9, x = -6, x = 10/3

That gives you the letters "joke"

Therefore, The letters corresponding to the solutions are: x = 10, x = -3/2, x = -1/9, x = -6, x = 10/3 That gives you the letters "joke"1.  5x – 7 = 4x + 3.

The temperature of the solution after four hours 1.4c

Temperature is measured with thermometers that may be calibrated to a variety of temperature scales because it is a relative measurement. For accurate measurement of temperature, scales based on reference points must be used. There are three main scales commonly used to measure the temperature:

The Fahrenheit scale, whose symbol is (°F).

The Celsius scale, whose symbol is (°C).

The Kelvin scale, whose symbol is (K).

Each of these scales has different reference points and uses a different set of divisions based on them. The Celsius scale is generally used for most temperature measuring purposes.

A chemist is observing a solution temperature over a four-hour period

that starts at -12.4c. in the four hours,

the temperature rises 5.7c

Answer:

a. Velocidad = 16 m/s

b. Deceleración = 0.64 m/s²

Step-by-step explanation:

Dados los siguientes datos;

Tiempo = 25 segundos

Distancia = 400 metros.

a. Para encontrar la velocidad;

Velocidad = distancia/tiempo

Velocidad = 400/25

Velocidad = 16 m/s

b. Para encontrar la desaceleración;

Durante una desaceleración, la velocidad inicial es mayor que la velocidad final.

Deceleración = (v - u)/t

Sabemos que la velocidad final es igual a cero (0) porque el automóvil se detiene.

Deceleración = (0-16)/25

Deceleración = 16/25

Deceleración = 0.64 m/s²

assuming you means k = log_2(3) [as log(2)3 is the same thing as 3log(2) due to multiplication being commutative]

The midpoint of the line segment with endpoints (-1, -6) and (4, 5) is (3/2, -1/2).

The midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is given by the coordinates:

((x1 + x2)/2, (y1 + y2)/2)

In this case, the endpoints are (-1, -6) and (4, 5), so we can plug in the values:

((x1 + x2)/2, (y1 + y2)/2) = ((-1 + 4)/2, (-6 + 5)/2)

Simplifying this expression, we get:

((x1 + x2)/2, (y1 + y2)/2) = (3/2, -1/2)

Therefore, the midpoint of the line segment with endpoints (-1, -6) and (4, 5) is (3/2, -1/2).

What is a system of equations?

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

Here, we have

Given: 3a - 5b = -26, a + 2b = 6

We have to solve this equation.

3a - 5b = -26...(1)

a + 2b = 6...(2)

Now we multiply equation (1) by 2 and equation (2) by 5 and we get

6a - 10b = -52....(3)

5a + 10b = 30....(4)

After solving equations (3) and (4), we get

11a = -22

a = -2

Now we put the value of 'a' in equation(3) and we get

6(-2) - 10b = -52

-10b = -52 + 12

-10b =  -30

b = 3

Hence, the value of a = -2 and b = 3.

(x, y) is an element of the set c × d, since x is an element of c and y is an element of d.

Since (x, y) was an arbitrary element in a × b, we can conclude that every element in a × b is also in c × d. Thus, we have shown that if a ⊆ c and b ⊆ d, then a × b ⊆ c × d.

To show that if a ⊆ c and b ⊆ d, then a × b ⊆ c × d, follow these steps:

Step 1: Understand the notation.
a ⊆ c means that every element in set a is also in set c.
b ⊆ d means that every element in set b is also in set d.

Step 2: Consider the Cartesian products.
a × b is the set of all ordered pairs (x, y) where x ∈ a and y ∈ b.
c × d is the set of all ordered pairs (x, y) where x ∈ c and y ∈ d.

Step 3: Show that a × b ⊆ c × d.
To prove this, we need to show that any ordered pair (x, y) in a × b is also in c × d.

Let (x, y) be an arbitrary ordered pair in a × b. This means that x ∈ a and y ∈ b.

Since a ⊆ c, we know that x ∈ c because every element in set a is also in set c.
Similarly, since b ⊆ d, we know that y ∈ d because every element in set b is also in set d.

Now, we have x ∈ c and y ∈ d, so the ordered pair (x, y) belongs to c × d.

Step 4: Conclusion
Since any arbitrary ordered pair (x, y) in a × b also belongs to c × d, we can conclude that a × b ⊆ c × d.

Therefore, the seventh number is 101.

Explanation:
Let x be the seventh number. We can set up the equation:
(6*38 + x)/7 = 47
Simplifying this equation, we get:
228 + x = 329
Subtracting 228 from both sides, we get:
x = 101
To solve this problem, we need to use the formula for the average of a set of numbers, which is the sum of the numbers divided by the number of numbers. We know the average of the first six numbers is 38, so the sum of those numbers is 6*38 = 228. When the seventh number is included, the sum becomes 6*38 + x, where x is the seventh number. We can set up an equation with this sum and the new average of 47, and solve for x. The solution is x = 101, so the seventh number is 101.

Therefore, the seventh number is 101.

Answer:

Step-by-step explanation:

The correct answer is: There will be a shortage of 3 yogurts.

The price ceiling of $3 is below the equilibrium price of $50. This means that there will be more people who want to buy yogurt at $3 than there are people who are willing to sell yogurt at $3. This will create a shortage of yogurt. The amount of the shortage is equal to the difference between the quantity demanded and the quantity supplied. In this case, the quantity demanded is 5 yogurts and the quantity supplied is 4 yogurts. Therefore, the shortage is 3 yogurts.

The other two answers are incorrect. The quantity demanded will not be 4 yogurts because 4 is below the equilibrium quantity of 5. The quantity supplied will not be 5 yogurts because 5 is above the price ceiling of $3.

The arc length of the given function over the interval [1,4e] is approximately 281.74 units.

The formula for arc length is given by: L = ∫[a,b]√(1+(dy/dx)²) dx

Using the given function y = 14x² - 12lnx, we can find the derivative: dy/dx = 28x - 12/x

Now, plugging this derivative into the formula for arc length and evaluating over the interval [1,4e], we get:

L = ∫[1,4e]√(1+(28x-12/x)²) dx

This integral cannot be evaluated in closed form, so we must use numerical methods to approximate the answer. One common method is to use Simpson's rule, which gives: L ≈ (4e - 1)/6 [√(1+(28(1)-12/1)²) + 4√(1+(28(2)-12/2)²) + 2√(1+(28(4e)-12/4e)²)]

Answer:

\(150( {1.01}^{12} ) - 150 = 19.02\)

The account will earn $19.02 interest in 12 months.

Answer:

Step-by-step explanation:

To determine the future value of the savings account after 12 months, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = the future value of the account

P = the principal or initial value of the account (in this case, $150)

r = the annual interest rate (1% per month or 0.01)

n = the number of times the interest is compounded per year (12)

t = the time period in years (1)

Plugging in these values, we get:

A = 150(1 + 0.01/12)^(12*1)

A = 150(1.0075)^12

A = $162.89

Therefore, the savings account will be worth approximately $162.89 after 12 months with 1% monthly interest. It is important to note that this is only an estimate, as the actual amount could vary depending on any additional deposits or withdrawals made during the year, and the interest rate could also change.
