. If y varies directly with x, and y = -35 and x=7, what is x when y = -85?
sertanlavr [38]

Answer:

x = 17

Step-by-step explanation:

Direct variation is given by

y = kx  where k is the constant of variation

-35 = k*7

-35/7 = k

-5 = k

y = -5x

We know y = -85

-85 = -5x

Divide each side by -5

-85/-5 = x

17 =x
