Answer:

x = -3

y = 9

Step-by-step explanation:

you can add the equations after multiplying the first one by 8

8x - 8y = -96  added to -8x - 4y = -96

'x' eliminated;  -12y = -108;  y = 9

Solve for 'x':

x - 9 = -12

x = -12 + 9

x = -3

Answer: 105

Given:

A video game customers to rent games for $4.75 each.

Customers can also buy a membership for $54 annually, and video games would only cost $2.50 each.

To find:

The number of video games a customer would have to rent in a year in order for the two options to be equal.

Solution:

Let x be the number of video games.

A video game customers to rent games for $4.75 each. So, the total cost is

[tex]C_1(x)=4.75x[/tex]

Customers can also buy a membership for $54 annually, and video games would only cost $2.50 each. So, the total cost is

[tex]C_2(x)=54+2.50x[/tex]

Now, [tex]C_1(x)=C_2(x)[/tex], if the rent in a year for the two options to be equal.

[tex]4.75x=54+2.50x[/tex]

[tex]4.75x-2.50x=54[/tex]

[tex]2.25x=54[/tex]

Divide both sides by 2.25.

[tex]x=\dfrac{54}{2.25}[/tex]

[tex]x=24[/tex]

Therefore, the rent in two options are equal for 24 video games.

Answer:

B. 68.5 & 76.5

Step-by-step explanation:

In order to solve this equation you first need to change your equasion to fit 2 scenarios. So, your 2 equations are x-72.5=4 and x-72.5=-4. From there, you need to solve by adding 72.5 to each equation giving you x=76.5 and x=68.5. 68.5 degrees F is your minimum temperature and 76.5 degrees F is your maximum temperature. I have included a screenshot of my handwritten work included below for those who are visual learners.

Answer:

B) 0.4 (6 - 2w)

Step-by-step explanation:

You can only add or subtract with the numbers that have the same variable:

You can only add -2.2w and 1.4w

Which is -0.8w

Then add 4.8 and -2.4

Which is 2.4

Now the equation is -0.8w+2.4 or 2.4-0.8w

0.4 times 6 is 2.4

0.4 times 2w is -0.8w

Which is the same

-0.8w+2.4 or 2.4-0.8w

Hope this helps!

Answer:

As part of exploring how functions change, we can identify intervals over which the function is changing in specific ways. We say that a function is increasing on an interval if the function values increase as the input values increase within that interval. Similarly, a function is decreasing on an interval if the function values decrease as the input values increase over that interval. The average rate of change of an increasing function is positive, and the average rate of change of a decreasing function is negative.

The image below shows examples of increasing and decreasing intervals on a function.

Given:

Cory made 21 of the 60 baskets she attempted.

Krista made 16 out of 40 baskets she attempted.

Paul made 17 of the 50 baskets she attempted.

Sally 11 of the 55 she attempted.

To find:

Who had the greatest percentages of baskets made?

Solution:

We know that,

[tex]\text{Percentage of baskets made}=\dfrac{\text{Baskets made}}{\text{Total attempts}}\times 100[/tex]

Using this formula, we get

[tex]\text{Cory's percentage of baskets made}=\dfrac{21}{60}\times 100=35\%[/tex]

[tex]\text{Krista's percentage of baskets made}=\dfrac{16}{40}\times 100=40\%[/tex]

[tex]\text{Paul's percentage of baskets made}=\dfrac{17}{50}\times 100=34\%[/tex]

[tex]\text{Sally's percentage of baskets made}=\dfrac{11}{55}\times 100=20\%[/tex]

From the above percentages 40% is maximum.

Therefore, Krista has greatest percentage of baskets made.

Answer:

The average rate of change of the function for the interval [-4, 0] is  [tex]\frac{3}{4}[/tex] ⇒ A

Step-by-step explanation:

The average rate of change of the function is the slope of the line that represents the function, m = Δy/Δx, where

From the given figure

→ The values of x in the interval [-4, 0] are -4 and 0

∵ The point (-4, 0) and (0, 3) lie on the line

∴ x1 = -4 and x2 = 0

∴ x2 = 0 and y2 = 3

∵ Δx = 0 - (-4) = 0 + 4 = 4

∵ Δy = 3 - 0 = 3

→ By using the rule of the slope above

∴ m = [tex]\frac{3}{4}[/tex]

∵ The average rate of change of the function = the slope of the line

∴ The average rate of change of the function for the interval [-4, 0] is  [tex]\frac{3}{4}[/tex]

The area of the right-angle triangle will be 1/18 square inches.

The area of the right-angle triangle is given as,

A = 1/2 x B x H

Where B is the base and H is the height of the right triangle.

The height of the right-angle triangle is 1/6 inch. And the base length of the right-angle triangle is 2/3 inches. Then the area of the right-angle triangle is given as,

A = (1/2) x (1/6) x (2/3)

A = 2 / 36

A = 1/18 square inches

The area of the right-angle triangle will be 1/18 square inches.

Answer: y= -4x^2

Step-by-step explanation:

The equation of the parabolic function is y = -4x² and the graph is plotted

A Parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. A parabola is a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line

The equation of the parabola is given by

( x - h )² = 4p ( y - k )

y = a ( x - h )² + k

where ( h , k ) is the vertex and ( h , k + p ) is the focus

y is the directrix and y = k – p

The equation of the parabola is also given by the equation

y = ax² + bx + c

where a , b , and c are the three coefficients and the parabola is uniquely identified

Given data ,

Let the parabolic equation be represented as f ( x )

Now , the value of f ( x ) = y

where y = -4x²

The equation y = -4x² represents a parabola that opens downwards (since the coefficient of x² is negative).

The vertex of this parabola is at the origin (0,0), since the coefficient of x is zero. The axis of symmetry is the y-axis, since the parabola is symmetric about this line.

Hence , the equation is y = -4x²
