Question

y varies inversely as the square of x. When x = 6, y = 4. Find y when x = 2.

Answer 1

\[y=\frac{k}{x^2}\]

Answer 2

Plug in x = 6 and y = 4 and find k.

Answer 3

@jabnwalker, this is the same problem I just helped you with, but in this case the original expression, as given by @Mertsj, shows that y varies inversely with x^2.

Answer 4

k=144

Answer 5

Now replace x with 2 and find y
