Mrs. Snedigar has a rectangle shaped back yard. If the length of her yard can be represented by 5x^2+x-25x 2 +x−2 and the width can be represented by 10x+510x+5. The following polynomial represents the perimeter of the yard, ax^2+bx+cax 2 +bx+c. Find the values of a, b, and c that represent the perimeter of the pool. a = , b = , and c =

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

exactly you go it
