1. The problem statement, all variables and given/known data Assume x and y are functions of t. Evaluate dy/dt for each of the following. xy-5x+2y^3=-70, dx/dt=-5 x=2 y=-3 2. Relevant equations n/a 3. The attempt at a solution I used x' and y' for dx/dt and dy/dt I found the derivative of the equation, using the product rule for xy (x)(yy')+(y)(xx')-5+6y^2=0 From here, my problem was figuring out how to simplify the equation... (x)(yy')=5-6y^2-yxx' y'= The answer was -5/7...I'm pretty sure I messed up on solving the equation for 0 and y'
