For implicit differentiation, you are using the chain rule

Except u(x) = y, So after every "y" term is differentiated it will be multiplied by dy/dx.
17)

Then you solve for dy/dx as if its a variable.

18) Here lets review product rule:

Take derivative of each term

Solve for dy/dx using factoring:
Answer: 156
Step-by-step explanation: 52*3=156 tickets
Answer:
My answer would be y=2x+1
Step-by-step explanation:
For this case we have the following expressions:
70,000,000
7,000,000
If we divide the first expression by the second we have:

Thus, we have that the first expression is 10 times greater than the second expression.
Answer:
70,000,000 is 10 times greater than 7,000,000
Answer:
90.00 increased by 20% is 108.00
The increase is 18.00
