To find the price of the video game with the coupon, subtract the discount amount from the original price.

To calculate the price of the video game with the coupon, we first calculate the discount amount. The coupon is for 25% off, so the discount amount is 25% of $100. Using the formula discount = (percentage / 100) * original price, the discount amount is (25 / 100) * $100 = $25.

To find the price of the video game with the coupon, we subtract the discount amount from the original price. The price of the video game with the coupon is $100 - $25 = $75.

Therefore, the price of the video game with the coupon is $75.

Answer: 53 cars were washed.

Step-by-step explanation:

Given : The unit rate comparing dollars earned to cars washed is 6.

i.e. The fundraiser can earn $6 per car wash.

If the fundraiser earned $318, then the number of car wash he did is given by :-

[tex]\dfrac{318}{6}=53[/tex]

Hence, 53 cars were washed.

Answer:

I'm not sure you put the right information for this one, because

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 = 36

so, to find the next number that equals 60, we have to subtract 60 to 36.

60 - 36 = 24

The answer to this question is zero 0

19x - 6x + 2

Two terms have an X in them, so you can combine them :

19x -6x = 13x

You now have 13x +2, which can be rewritten as 2 + 13x

The 3rd answer is correct.

Hey there!

The correct choice is C. 2 + 13x

Like the answer says, all you have to do is combine the x’s and rearrange: 13x +2 can be rearranged as 2 + 13x

Hope this helps you!

Answer:

The missing value is 5

The solution is (8,5)

Explanation:

The given equation is:

5x - 2y = 30

An order pair is written as (x , y). We are given (8 , ?)

This means that we want to find the y value that corresponds to x=8

To do this, we will substitute with x=8 in the given equation and solve for y

This is done as follows:

5x - 2y = 30

5(8) - 2y = 30

40 - 2y = 30

2y = 10

y = 5

This means that at x=8 and y=5, the equation is satisfied

(8,5) is a solution to the given equation

Hope this helps :)

Answer:

(8, 5)

Step-by-step explanation:

The given equation is:

5x - 2y = 30

We have to complete the given incomplete solution set (8, ?)

The first point in the ordered pair is always the x-value. So we are given an x-value and we have to find the corresponding y-value from the function.

Using x = 8 in the given function, we get:

5(8) - 2y = 30

40 - 2y = 30

- 2y = 30 - 40

- 2y = -10

y = 5

So, the value of y for x = 8 is 5. The complete ordered pair that satisfy the equation will be (8, 5)

a. true

b. true

c. true

Answer:

$50

Step-by-step explanation:

x is the total cost of the game

You can see that 3×10 =30

So, 5×10 would be x.

Therefore, x equals to 50.

Subtract 3 from both sides:

7r = 56

Divide both sides by 7:

r = 8

The graph that represents the line (y = 12x) is option C) and this can be determined by using the point-slope form of the line.

Given :

Bike traveling at a constant rate of 12 miles per hour.

The following steps can be used to determine the graph that represents a bike traveling at a constant rate of 12 miles per hour:

Step 1 - All the graphs in the option pass through the point (0,0). So, (0,0) is the point through which a line is pass through.

Step 2 - Another point is (1,12) through which line passes because it is given that bike traveling at a constant rate of 12 miles per hour.

Step 3 - The equation of the line that passes through the points (0,0) and (1,12) is given by:

[tex]\dfrac{y-0}{x-0}=\dfrac{12-0}{1-0}[/tex]

y = 12x

So, the graph that represents the line (y = 12x) is option C).

The graph of the circle is given in the image attached

To graph the circle represented by the equation x^2 + (y+3)^2 = 9, identify the center at (0,-3) and radius 3, then plot the center and draw the circle on a graph.

The student's question relates to the equation of a circle in Cartesian coordinates and how to graph it. Given the equation x2 + (y+3)2 = 9, we can determine the center and the radius of the circle it represents. To graph the circle, first identify the center, which in this case is at (0, -3), because the equation can be written in the standard form (x - h)2 + (y - k)2 = r2 where (h, k) is the center and r is the radius. Then find the radius by taking the square root of the right side of the equation, which is 3 in this case.

Plot the center on the Cartesian graph, and draw a circle around it with a radius of 3 units, ensuring that possible points on the circle follow the equation such as (0,0), (-3,-3), and (3,-3) for instance.

F(x)=(x+1)^2 that’s the answer

Answer:

[tex]f(x)=(x+1)^2[/tex]

Step-by-step explanation:

We have been given graph of a function. We are asked to find the equation of the graphed function.

Upon looking at our given graph, we can see that the graph represents a parabola.

We know that vertex form of a parabola is: [tex]y=a(x-h)^2+k[/tex], where, (h,k) represents the vertex of parabola.

We can see that vertex of our given parabola is at point [tex](-1,0)[/tex], so substituting the coordinates of vertex of parabola, we will get:

[tex]y=a(x--1)^2+0[/tex]

[tex]y=a(x+1)^2[/tex]

Now we will find the value of a using coordinates of point (0,1) in above equation.

[tex]1=a(0+1)^2[/tex]

[tex]1=a(1)^2[/tex]

[tex]1=a*1[/tex]

[tex]1=a[/tex]

Therefore, the equation of our graphed function would be [tex]f(x)=(x+1)^2[/tex]

Answer:

15 < n < 25

Step-by-step explanation:

According to the triangle inequality theorem, any two sides lengths' sum should be greater than the third side. This also implies that to find the possible length of  the 3rd side given other two sides (let two given sides be x and y), we can say that the 3rd side length will be between x+y and x-y.

Hence, we can say that n should be between 20+5 and 20-5.

So, 20 - 5 < n < 20 + 5, which is

15 < n < 25

This is the correct answer.

Answer:

15 < n < 25 which on ed is D

Step-by-step explanation:

According to the triangle inequality theorem, any two sides lengths' sum should be greater than the third side. This also implies that to find the possible length of  the 3rd side given other two sides (let two given sides be x and y), we can say that the 3rd side length will be between x+y and x-y.

Answer:

The answer is P(0,4) , Q(2,0)

Step-by-step explanation:

Points P and A are any coordinates where y = 4 - 2x. For example, P might be the point (1, 2).

The given equation is 4x + 2y = 8. To find the coordinates of points P and A, we can rearrange and simplify the linear equation. Divide the whole equation by 2, we get 2x + y = 4, or y = 4 - 2x. Therefore, the line has the slope-intercept form of y = mx + b, where m is the slope and b is the y-intercept. This line passes through all points (x, y) where y = 4 - 2x. Therefore, P and A can be any points satisfying this equation. For example, if x = 1, then y = 2, so one possible coordinate is P(1, 2).

The answer would be 11

The answer is B.

This is because the formula is length × width.

So the 3 formulas we would have are 2 × 4, 4 ×3, and 3 × 2.

This means your possible answers are 8, 12 and 6.

The only answer that matches up is 6 or B.

In order to answer 23, you have to include 22 in the picture. The answer to 24 is 3 times 11+6, and Kayla earns $351.

Step-by-step explanation:

Answer: $351

Step-by-step explanation:

f(x) = 3x + 6                 g(x) = x - 2

(f · g)(x) = (3x + 6)(x - 2)

             = 3x² - 6x + 6x - 12

             = 3x² - 12

(f · g)(11) = 3(11)² - 12

The height from the ground increases from 4 to 26, then decreases from 26 to 0.

Why the others are wrong.

A. The height of the rocket changes at a constant rate for the entire time.

The graph is a curve. This means the rate is not constant. If it were constant, the graph would be linear - a straight line.

C. The height of the rocket remains constant for some time.

The graph is a curve. This means the rate is not constant. If it were constant, the graph would be linear - a straight line.

D. The height of the rocket decreases for some time and then increases for some time.
