How to find the derivative of the below question?

Given:

To find:

The derivative of the given problem.

Solution:

Chain rule :

Quotient rule :

We have,

Differentiating with respect to x using chain rule and quotient rule, we get

Therefore, the required derivative is .

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
