What is the slope of the line through the points (-2, -1) and (4, 3)
5/2
3/2
2/5
2/3

2/3

Step-by-step explanation:

hope this help:) I use slop formula

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

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
