Step-by-step explanation:

You want to set one of the equations equal to either x or y. For this, I put x+y=-2 equal to y which would be y=-x-2. Then you plug this in to the other equation for y. This would give you 5x+2(-x-2)=2. When you factor the two into the parenthesis, combine like terms, and keep the x values on ones side and the other numbers on the other side, you get 3x=6

Answer:

B. $H(x)=-.008(x-82)^{2}+83$

Step-by-step explanation:

Well lets graph the following equation first,

H(x) = -.011(x - 82)^2 + 75

Then lets graph all the other equations.

Look at the image below↓

So A.

The purple line does not go farther or higher,

so A. is incorrect

The black line goes higher and farther,

meaning it is correct.

The red line goes farther but not higher.

So it is incorrect

Again the blue line does not go farther of higher.

So its wrong.

Thus,

answer choice B. $H(x)=-.008(x-82)^{2}+83$ is correct.

Hope this helps :)

Answer: M=-2 , B= 2 , Equation: Y= -2x+2

Step-by-step explanation:

M is the slope. Slope is "rise / run", so 2 over -1. simplified, that is -2. B is the y-intercept, or where the graph crosses the y-axis. So, b will be 2.

At a pizza eating competition, Davonne ate four more than twice as many slices as the runner up. If Davonne ate 11 slices, then

Sauron [17]

Let's begin with x as the number of slices the runner up ate.
Davonne ate four more than twice
So the equation should look somewhat like this.
4+2x=11
2x=7
x=3.5
So the runner up ate 3.5 slices
Davonne ate four more than twice as many slices as the runner up. If Davonne ate 11 slices, then how many slices did the runner up eat?
