Suppose that y varies inversely with x. What’s an equation for the inverse variation , y=3 when x=6

Question

algebra 2.

Answer 1

Remember that the general formula for inverse variation is xy = k, where k is some constant

or y = k/x

In this case, determine k using the given values:

xy=k

6 x 3 = k

18 = k

So your equation can be either xy = 18 or y = 18/x (which are equivalent expressions) <---ANS
