The given information were that Robi has run the first 4 miles of a race in 30 minutes and she reached the 6 mile point after 45 minutes. It is positive, negative, zero or undefined? The slope is 2/15 miles/minute

Positive

Step-by-step explanation:

Slope: (6-4)/(45-30)

= 2/15

the answer is 37

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
