How are graphs with k > 0 different from graphs with k < 0?

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
