Answer:

Step-by-step explanation:

The complete question in the attached figure

Let

x ----> the number of movies

y ----> the amount of money remaining on her gift card

we know that

The slope of the linear equation is equal to the unit rate

take two points from the graph

(0,18) and (2,12)

Find the slope

---> is negative because is a decreasing function

That means -----> Each movie she rents cost her $3, so her  gift card balance will decrease $3 for every movie rented

The linear equation is equal to

For y=0

so

6 is the maximum number of movies that Elyse can rent on line

The solution is

a) The equation of line is y = -3x - 6

b) The y-intercept of the line is -6 which means when the number of movies x = 0 , the amount on gift y = -6

c) The slope of the line is -3 which means the rate of change of amount on gift is decreasing with number of movies x

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

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

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be A

The value of A = A ( 2 , 12 )

Let the second point be B = B ( 4 , 6 )

a)

Now , the slope of the line is given by the equation

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

On substituting the values in the equation , we get

Slope m = ( 6 - 12 ) / ( 4 - 2 )

Slope m = -6/2

Slope m = -3

Therefore , the slope is -3

The equation of line is given by the formula

y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 12 = -3 ( x - 2 )

On simplifying the equation , we get

y - 12 = -3x + 6

Adding 12 on both sides of the equation , we get

y = -3x - 6

So , the equation of line is y = -3x - 6

b)

The y intercept of the equation of line y = -3x - 6 is -6 , when x = 0

c)

The slope of the line y = -3x - 6 is m = -3 and the value is decreasing

Hence ,

a) The equation of line is y = -3x - 6

b) The y intercept of the equation of line y = -3x - 6 is -6

c) The slope of the line y = -3x - 6 is m = -3

Answer:

Step-by-step explanation:

To solve this, use the Pythagorean Theorem: a² + b² = c². You insert the measurements you have: 3² + b² = 5² or 9 + b² = 25. To solve this, subtract 9 from both sides: b² = 16. To solve for b (length) specifically, find the square root of 16: 4.

Step-by-step explanation:

A quadratic function has the possibility of two x-intercepts.

A quadratic function is one of the form f(x) = ax² + bx + c, where a, b, and c are numbers with a not equal to zero.

Given that a function having two x-intercepts

The graph of a quadratic function will always have one y-intercept and can have as many as two x-intercept.

Hence, a quadratic function has the possibility of two x-intercepts.

Answer:

[tex]x^2 + y^2 - 40 = 0[/tex]

Step-by-step explanation:

Given

[tex](h_1,k_1) = (6,-2)[/tex]

[tex](h_2,k_2) = (-6,2)[/tex]

Required

Determine the equation of the circle

First, calculate the midpoint of the given coordinates:

[tex](h,k) = \frac{1}{2}(h_1+h_2,k_1+k_2)[/tex]

[tex](h,k) = \frac{1}{2}(6-6,-2+2)[/tex]

[tex](h,k) = \frac{1}{2}(0,0)[/tex]

[tex](h,k) = (0,0)[/tex]

Next, calculate the radius.

This is the distance between [tex](0,0)[/tex] calculated above and any of [tex](6,-2)[/tex] [tex](-6,2)[/tex]

Using:

[tex](0,0)[/tex] and [tex](-6,2)[/tex], the radius is:

[tex]r = \sqrt{(0 - (-6))^2 + (0-2)^2}[/tex]

[tex]r = \sqrt{40}[/tex]

The equation is then calculated using:

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

Where:

[tex]r = \sqrt{40}[/tex] and [tex](h,k) = (0,0)[/tex]

[tex](x - 0)^2 + (y - 0)^2 = (\sqrt{40})^2[/tex]

[tex](x )^2 + (y)^2 = 40[/tex]

[tex]x^2 + y^2 = 40[/tex]

[tex]x^2 + y^2 - 40 = 0[/tex]

Answer:

The box is 5 inches tall

Step-by-step explanation:

The given dimensions of the video games are;

The length of the video game, L = 15 inches

The width of the video game, W = 10 inches

The volume of the video game box, V = 750 cubic inches

Assuming that the shape of the video game box is a cuboid, we have;

The formula for the volume of a cuboid, V = Length, L × Width, W × Height, H

∴ V = L × W × H

The height of the cuboid, H = V/(L × W)...(1)

Where, for the video game box;

L = Length = 15 in.

W = Width = 10 in.

V = Volume = 750 in.³

Plugging in the values of the variables in equation (1) gives;

H =  V/(L × W) = 750 in.³/(15 in. × 10 in.) = 5 in.

The height of the box, H = 5 inches.

Answer:

Third week = 23.35 miles

Step-by-step explanation:

First week total miles = 15 miles

he would like to run 30% more miles each week than the week before

Second week = 15 miles + (30% of 15 miles)

= 15 + (30% * 15)

= 15 + (0.3 * 15)

= 15 + 4.5

= 19.5 miles

Second week = 19.5 miles

Third week = 19.5 miles + (30% of 19.5 miles)

= 19.5 + (30% * 19.5)

= 19.5 + (0.3 * 19.5)

= 19.5 + (5.85)

= 23.35 miles

Third week = 23.35 miles
