You could think about the way the language works, and then answer each of those yourself.


a varies jointly as b.....
a=kb

a varies directly with b.....
a=kb

a varies inversely with b....
a=k%2Fb

and you can use that to figure how other types within this also work.

Try to identify as many as you can on your own,
and post your results to the forum.

We will check it for free.

Also, make editing in your equation (c), it is written incorrectly.
