<h2>Answer: x=-2(-y+4)</h2>

Step-by-step explanation:

-2x+4y=16

Subtract 4y from both sides

-2x+4y-4y=16-4y

Simplify

-2x=16-4y

Divide both sides by -2

-2x/-2=16/-2- 4y/-2

Estimate the instantaneous rate of change at the point indicated. (Round your answer to four decimal places.) y(x) = 1 x + 2 ; x

Wittaler [7]

Answer:

-1/36

Step-by-step explanation:

Estimate the instantaneous rate of change at the point indicated

To find the instantaneous rate of change we find the derivative of the given function

Instantaneous rate of change is the rate of change at the given point

$f(x)=\frac{1}{x+2}$

To find derivative we apply power rule

$f(x)=(x+2)^{-1}$

$f'(x)=-1(x+2)^{-2}$

$f'(x)=\frac{-1}{(x+2)^2}$

Now plug in 4 for x in f'(x)

$f'(4)=\frac{-1}{(4+2)^2}$

$f'(4)=\frac{-1}{36}$

Area/4 = Shaded

18/4 = Shaded

4.5 = Shaded

Hope this helps!
