So, suppose $y=2x+1$ , where $x$ and $x$ are functions of $x$. if $\frac{dx}{dt}=3$, find $\frac{dy}{dt}$ when $x=4$. $dydt=$

If $y=2x+1$, then $dy/dt=2\left(dx/dt\right)$.
if $dx/dt=3$, find $dy/dt$ when $x=4$:
Replacing $dx/dt$ with $3$ in $dy/dt=2\left(dx/dt\right)$ yields $dy/dt=2\left(3\right)=6$
