If you drive your car for three hours on average speed of 130 km per hour how far did you go

answer: .75 km

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
