Jameson runs m miles and burns c number of calories is this independent or dependent

the amount of miles he runs (m) is independent and the number of calories (c) he burns is dependent

the answer to the question is a  

it has the same slope and the same y-intercept.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
