Rate of proportionality for (-2,4) and (-1,1)

-3

Step-by-step explanation:

This is just another word for slope

y-y over x-x

y: 4-1 =3

x: -2 - (-1)= -1

so 3/-1 which reduces to -3

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

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
