Suppose the y varies inversely with x. Write an equation for the inverse variation. y = 4 When x = 7

Answer 1

Since y varies inversely with x, we know that the equation for inverse variation is: y = k/x, where k is the constant of variation.

Given that when x = 7, y = 4, we can plug these values into the equation to solve for k:

4 = k/7
k = 28

Therefore, the equation for the inverse variation is y = 28/x.
