4/5z=16 solve equation (that's a fraction )

1 answer:

6 0

So we need to isolate the variable. In order to do that, we need to multiply both sides by 5/4.
Why? That's so that 4/5z will be canceled out when multiplied by 5/4 to get just z.
And so, we would get 20 as our answer.

Find the first derivative of x^2+y^2=25

lozanna [386]

Answer:

$\frac{dy}{dx}=-\frac{x}{y}$

Step-by-step explanation:

Use implicit differentiation:

$x^2+y^2=25\\\\2x+2y\frac{dy}{dx}=0\\ \\2y\frac{dy}{dx}=-2x\\ \\\frac{dy}{dx}=-\frac{x}{y}$

Remember to treat "y" as a constant in implicit differentiation and include dy/dx.
