Evaluate $frac{dy}{dt}$ for the function at the point.
1) $x^2e^y - y^2 ln x = 6$; $frac{dx}{dt} = 1$, $x = 1$, $y = 3$
2) $xy^2 = 4$; $frac{dx}{dt} = -5$, $x = 4$, $y = 1$
Provide an appropriate response.
3) If $x^3 + y^3 = 9$ and $frac{dx}{dt} = -3$, then what is $frac{dy}{dt}$ when $x = 1$ and $y = 2$?
