what do you think

anonymous · Answer

plugging in, y=z/x

jordan123321 · Answer

your correct and no im not

anonymous · Answer

I know something has to plug in...

anonymous · Answer

wait a sec "y varies jointly as x and the cube of z" so would I plug in x and y in the y=xz^3??

nnesha · Answer

*jointly* do you know what equation you should use ??
and there suppose to be *k" in the equation

anonymous · Answer

no im not sure...
I know I have to find k, but not sure how

nnesha · Answer

*jointly* is use only for direct variation 
which means that it suppose to be y = kx form
so |dw:1426902783832:dw| equation
