(a) If dx/dt = 9, find dy/dt when x = 4.

OpenStudy (loser66):

what is the relationship between x and y? are they married yet?

OpenStudy (anonymous):

no they are derivatives of each other

OpenStudy (loser66):

wow, it's weird, I think I fail on this problem, let's get others' help @SolomonZelman @shamil98 @BlackLabel

OpenStudy (anonymous):

well i think we can assume that the y axis is f(x)?

OpenStudy (anonymous):

so the derivative of x with respect to t is 9 so we can multiply by dt right?
