First differentiate the whole equation with respect to t Next plug dy/dt = 6 x=1/5 and y = 1/5 then find dx/xt
\[2x^3+3y^3=xy\] \[6x^2x'+9y^2y'=x'y+y'x\] isolate x' \[x'(6x^2-y)=y'x-9y^2y'\] \[x'=(y'x-9y^2y')/(6x^2-y)\] plug in the appropriate values x=1/5, y=1/5, y'=6
so is it increasing or decreasing
I got 4.651 I don't think that right
