Question

. If y varies inversely as x and x = 6 when y = 30, then what is the constant of variation, k?*

Answer 1

Inverse variation is represented by the

formula xy = k where k is the constant of variation.

So here, since we know that x = 6 and y = 3,

the constant of variation must be equal to (6)(30) or 180.

So 180 = k.
