Alberto ran at a speed of 3 m/hr. After ran 6 miles , Omar ran in the same direction with a speed of 4.6 m/hr. Write a system of equations to mode the situation.

Alberto: y=
Omar: y=

Part B: solve the system to determine how many hours it will take Omar to catch up to Alberto.

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

i believe it's a.

i'm not sure on this one, most likely correct.

correct choice is a

step-by-step explanation:

the equation of the line passing through the points and is

thus, the equation of the line that passes through the points (0, -6) and (-3, 0) is
