Question 970536: I really need help with this fast!
The variable z varies jointly with x and y and inversely with the square of t. Also, z=5 when x=2, y=-3, and t=1/2. Write a function such that f(y)=t when x=-12/(5z)^2 and z=2/5.

f(y)=________
Thanks in advance!

You can put this solution on YOUR website!
z varies jointly with x and y and inversely with the square of t.

z=k%28xy%2Ft%5E2%29

That was "really...fast" help, as you asked.

The function you are looking for needs precise information. As given or asked so far, it is not understandable what you want or mean by f(y). Give the exact complete problem description, word-for-word.
