Question

For exercise, Guy walks on a treadmill. The number of miles he walks can be shown with a graph of the equation y = 4x, where x represents hours. How far does Guy walk in 3 hours of exercise?

A. 4 miles
B. 8 miles
C. 12 miles
D. 14 miles

Answer 1

C 12 miles

Answer 2

Nobody explains ANYTHING.

Answer 3

ok but how do you find it

Answer 4

The best way to find the answer is to plug in 3 to the equation and solve for Y. So, we know that y is the number of miles Guy will walk, right? And we know that x is the number of hours he's walking. Since y equals 4 times x, we have that y = 4 * 3 = 12.

Answer 5

Does that make sense?

Answer 6

x represents hours

equations is

y = 4x

so all you do is replace x with the number of hours which in the question is 3 hours

y = 4(3)

y = 12
