The numbers x^3 and y^3 are inversely proportional. If x = 2 when y = 15, what is y if x = 1 and y is positive? Write your answer in simplest radical form.

#3**+1 **

The numbers x^3 and y^3 are inversely proportional.

This is what that means

\(y^3=\frac{k}{x^3}\\ \)

Now sub in x = 2 when y = 15 and solve for k

Once you have k you can plug in x=1 and find the corresponding value of y

**Now you can answer yourself :)**

Please no one answer over me.
