Variation??!?!?

Question

I need help. Any would be greatly appreciated.

ok---

Z varies inversly with Y. Y varies inversly with X. How are X and Z related. How do you know?

Answer 1

Inversely means that one goes up while the other goes down.

If Z goes up while Y goes down,
and X does the opposite of Y,
then X is going up, just like Z is going up.
Going the same direction is varying directly.
