A triangle has side lengths of (6.1w+6.2)(6.1w+6.2) centimeters, (2.9w+3.4)(2.9w+3.4) centimeters, and (8.8x+7.6)(8.8x+7.6) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?

if x decreases by 4 then y increases by 10

step-by-step explanation:

a - base

b - exponent

so,

10 down (bang1)

5 up

5down (2)

2.5 up

2.5 down (3)

1.25 up

1.25 down (4)

now add them up : )

hoped i lol

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
