Answer:
yes 5 is right
Step-by-step explanation:
Hope it helps with your work
N(2x+y) = x +1
Differentiate both sides, using the Chain Rule on the left side.
(1 / (2x + y)) * d(2x + y)/dx = 1
(1 / (2x + y)) * (2 + dy/dx) = 1
<span>Rearrange to isolate dy/dx.

For this case we must indicate the cosine of A, of the figure shown. By definition:

Substituting the values we have:

So, we have to:
