Question

find a variation content and an equation of variation where y varies directly as x and y=72 when x=8

Answer 1

If y=kx where k is the variation constant, plug in your values and solve for k. And then the equation is just y=kx where you plug in your value for k.

Answer 2

so the variation constant is k=

Answer 3

y=kx thus 72=k8 solve for k.

Answer 4

im lost

Answer 5

You need to get k by itself. So 72=k8 if we divide both sides by 8 we get k.
