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.
+118667 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.
