Yes!

Answer 6

@Annetta_Martin If y varies inversely with x, then
\[y=\frac kx \]
k is a constant

As x increase, y decreases
if x decreases, then y increases
So do you understand till here?

Answer 7

Yes, I think I can take it from here. I was just getting mixed up with the beginning. Thank you so much @ash2326! :)

Answer 8

No Problem :D

The beginning is always the hardest part in math
because you don't understand what the words mean.

Answer 10

I was trying to show you how to get around that problem while studying math in general, but now ash2326 has given you the recipe you don't need to know how to cook it up yourself.
