Question

If y varies inversely with x and y=8 when x=40, what is the constant of variation

Answer 1

Explanation:

Inverse Variation. Since k is constant, we can find k given any point by multiplying the x-coordinate by the y-coordinate. For example, if y varies inversely as x, and x = 5 when y = 2, then the constant of variation is k = xy = 5(2) = 10.
