. If y varies inversely as x and y = -4 when x = -2, find x when y = 2.

Answer 1

Hello Audrey,

Since y varies inversely with x, it means x•y = constant

You're told y = -4 when x = -2. You can use that to find the constant: x•y = (-4)•(-2) = 8.

You're asked to find x when y = 2. You know the constant is 8. So set up x•y = constant:

-----> x•2 = 8

Now, solve for x. You got this.
