Me! p. s. don't forget to show your work! solve the word problem. the formula t = gives the time t for a distance d traveled at a rate r. a train traveled 225 miles at a rate of 45 mi/hr. how long did it take the train to travel this far? a. 4.5 hr b. 5 hr c. 5.5 hr d. 6 hr

its me i need help with points

Step-by-step explanation:

d. 9

step-by-step explanation:

54/12 = 4.5

sf = 4.5

so x = 2 · 4.5 = 9

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
