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.

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

 

This is what that means    wink

 

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

 

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.
