Question

If y varies inversely as x, how do you find the constant of variation and the inverse variation equation given y=90 when x =6?

Answer 1

`y=540/x and x=540/y`.

Explanation:

`y=k/x`, where k is the constant ox proportionality.
y=90, when x=6. So, k = xy =540.
In this unique relation, the function `y^(-1)` is same as the function y.
