y =

Answers

Answer:

y=3x-8

Step-by-step explanation:

All you do is multiply the y-intercept which is -4 with the dilation of 2 which means multiply it by 2.

The dilated equation of a line by a factor of 2 is y = 3x - 4.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, line l has the equation y = 3x - 4.

We know when a line is dilated by a scale factor of k slope of that line remains the same only y-intercept b is multiplied by that scale factor k.

∴ y = 3x - 4 dilated by a scale factor of 2 is y = 3x - 8.

good buy electronics has a markup of 150% on a keyboard that cost the retailer $25. find the retail "selling" price and show your work

Answers

The retail selling price of the keyboard is $43.75.

What is the percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

To find the retail selling price of the keyboard, we need to add the markup to the cost of the keyboard.

The markup of 150% means that the retailer is adding 150% of the cost to the selling price.

To calculate this, we can first find the dollar amount of the markup:

Markup = 150% of $25

Markup = 0.5 * 150 * $25

Markup = $18.75

This means that the retailer is adding $18.75 to the cost of the keyboard to get the selling price. To find the selling price, we can add the markup to the cost:

Selling price = Cost + Markup

Selling price = $25 + $18.75

Selling price = $43.75

Therefore, the retail selling price of the keyboard is $43.75.

D. The relation is a function. The domain is {0,1,2,4,5,7}

Answers

Answer:

Step-by-step explanation:

The relation is not a function. All you need to solve this problem is the following: Relations are NOT functions when the domain values repeat!

Note: The domain is the set of input values. The domain is x, the first number in the pair. For example, in the pair (0, 2), the domain is 0.

In the relation {(0,2),(2,4),(1,7),(2,5)}, 2 is repeated two times, which, by definition, means that the relation is not a function.

There are 17 rows of seats in a cinema. There are 22 seats in each row. A film was shown in the cinema on friday night. Each ticket for the film cost £7.50
The sale of tickets for that night made £2587.50
How many tickets were not sold

Answers

Answer:

Step-by-step explanation:

345 tickets = 345 x 7.50 = £2587.5 this means 345 - 374 = 29

how to get 374:

17 x 22 = 374

29 tickets were not sold.

Given that,

There are 17 rows of seats in a cinema.

There are 22 seats in each row.

Each ticket for the film cost £7.50

The sale of tickets for that night made £2587.50

How many tickets were not sold?

According to the question,

There are 17 rows of seats in a cinema.

There are 22 seats in each row.

Each ticket for the film cost £7.50

The sale of tickets for that night made £2587.50

Then,

Total number of seats is,

= 17 x 22 = 374

Number of tickets sold = £2587.50 / £7.50 = 345

Therefore,

45 people filled 345 seats

Unoccupied seats = 374 - 345 = 29

Therefore, 29 tickets were not sold.

what steps are needed to find the equation of a line given the graph?

Answers

The equation of the line is y = x.

To find the equation of a line given its graph, you need to follow the steps below.

Step 1: Determine the slope of the line.The slope of the line can be determined using the formula: slope = rise/run or m = Δy/Δx. Rise is the change in the y-coordinates and run is the change in the x-coordinates.

Step 2: Determine the y-intercept of the line.The y-intercept is the point where the line intersects the y-axis. You can determine the y-intercept by looking at the point where the line crosses the y-axis on the graph. The y-intercept is denoted by the letter b.

Step 3: Write the equation of the lineThe equation of the line can be written in slope-intercept form, which is y = mx + b. The slope (m) and y-intercept (b) that were determined in steps 1 and 2 are used to substitute into this equation. Thus, the equation of the line becomes y = slope(x) + y-intercept.

Example:Let's say you are given the graph of a line below: ![image](https://media.education.com/images/060b2365-37a3-40fb-b6f2-cd7f2f84e2b2.jp g).

Step 1: Determine the slope of the line.To determine the slope of the line, you need to choose two points on the line and calculate the rise and run. Let's choose the points (2, 1) and (4, 3). The rise is 2 (3 - 1) and the run is 2 (4 - 2). Therefore, the slope of the line is: m = 2/2 = 1.

Step 2: Determine the y-intercept of the lineThe line crosses the y-axis at the point (0, 0). Therefore, the y-intercept of the line is b = 0.

Step 3: Write the equation of the line.The equation of the line in slope-intercept form is y = mx + b. Substituting the slope and y-intercept into this equation gives: y = 1x + 0 or y = x.

1/3 + 3/5 + 7/9 + 13/15

Answers

Answer:

116 / 45

Step-by-step explanation:

To add fractions with unlike denominators, we need to find their common denominator.

One way to do this is by finding the least common multiple (LCM) of the denominators.

The LCM of 3, 5, 9 and 15 is 45.

We then convert each fraction so that its denominator is 45:

1/3 = 15/45

3/5 = 27/45

7/9 = 35/45

13/15 = 39/45

Now we can add the fractions:

15/45 + 27/45 + 35/45 + 39/45

To simplify, we can add the numerators and keep the common denominator:

(15 + 27 + 35 + 39) / 45

Which gives us:

116 / 45

Therefore, the sum of the fractions 1/3 + 3/5 + 7/9 + 13/15 is, 116 / 45.

A ball thrown upwards hits a roof and returns back to the ground.
The upward movement is modeled by a function s=−t2+3t+4
and the downward movement is modeled by s=−2t2+t+7
, where s is the distance (in metres) from the ground and t
is the time in seconds.
Find the height of the roof from the ground.

Answers

Answer: To find the height of the roof, we need to find the point where the ball reaches the maximum height, i.e., the point where the velocity of the ball is equal to 0.

The velocity of the ball can be found by taking the derivative of the function s. The derivative of the function s = −t^2 + 3t + 4 is given by v = ds/dt = 3 − 2t, and the derivative of the function s = −2t^2 + t + 7 is given by v = ds/dt = 1 − 4t.

Setting v = 0, we get 3 − 2t = 0 and t = 3/2 seconds.

Plugging t = 3/2 seconds into the first equation, s = −t^2 + 3t + 4, we get s = −(3/2)^2 + 3(3/2) + 4 = 9/4 + 9/2 + 4 = 7 metres.

Therefore, the height of the roof from the ground is 7 metres.

Answers

$25635-$10000=$15635

ans; She will own the 4runner when she is 20 years old

Answer:

price of new car $25635

depreciation rate= $3000 / month

target price= $10000

daughters' age= 15 years old

time required= (25635-10000)/3000 ≈ 5.2 years

if a = 24cm, b = 36 cm, and c = 24cm, what is the area of the picture of the helmet?

Answers

Answer:

946.19 cm²

Step-by-step explanation:

Ok, we are going to split the shape into the semi-circle and the trapezoid:

Semi-Circle:

Here's the formula for the area circle: πr²

Because the semi-circle is just half of a circle, the area of a semi-circle :

(πr²) ÷2

Step 1: Input Information

The radius (r) is 1/2 the diameter (a) of the circle

Radius = 1/2(24) = 12

Now we have enough info to solve for the Area

Step 2: Solve for Area

A = (12²π) ÷2

A = (144π) ÷2

A = 72π

A ≈ 226.19

Area semi-circle is 226.19 cm²

Trapezoid

The formula for the area of a trapezoid is : h(b1 + b2) ÷ 2

The height (h) over here is c, or 24 cm

The base 1 (b1) is a, or 24 cm

The base 2 (b2) is b, 36 cm

Step 1: Input Information

Our new equation becomes:

A = c(a + b) ÷ 2

A = 24(24 + 36) ÷2

Step 2: Solve for area

A = 24(24 + 36) ÷ 2

A = 24(60) ÷ 2

A = 24(30)

A = 720

Area of the trapezoid is 720 cm²

Total Area:

Now, we just simply add the two values together

226.19 cm² + 720 cm² = 946.19 cm²

Answers

Hey there!

The answer is no, they would not return to the original price of $200.

This is because when you decrease 200 by 20%, you get 160. Then, if you increase 160 by 20%, you get 192. This is because 20% of 200 and 20% of 160 is different.
