How do you write the equation 4x + 2y = 16 in function form? Please answer with an explanation!

kramer

F(x)=-2x+8 This is because f(x) is the same as writing y so therefore you have to change the equation to 4x+2y=16 so you have Y=-2x+8

If xy + x = 12 and dx/dt = -3, then what is dy/dt when x = 2 and y = 5?

dlinn [17]

If $xy + x = 12$ , then
$\dfrac{d}{dt}(xy+x)= \dfrac{d}{dt}(12)$ .
Use the chain rule:
$y\dfrac{dx}{dt}+x \dfrac{dy}{dt}+ \dfrac{dx}{dt}=0$ ,
Since x=2, y=5, <span>dx/dt = -3, then
</span>
$5\cdot (-3)+2\cdot \dfrac{dy}{dt}+(-3)=0, \\ 2\cdot \dfrac{dy}{dt}=18, \\ \dfrac{dy}{dt}=9$ .
