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:
The third answer- a reflection over the x axis then a reflection over the y axis
if there are 4 numbers that average to 60, when mutiplied they must come up to: 60*4= 240
100+30+45= 175
240-175= 65
PROOF:
100+30+45+65= 240
240÷ 4
= 60
Step 1: Simplify both sides of the equation.
3(x−3)+5=3x+1+4
(3)(x)+(3)(−3)+5=3x+1+4(Distribute)
3x+−9+5=3x+1+4
(3x)+(−9+5)=(3x)+(1+4)(Combine Like Terms)
3x+−4=3x+5
3x−4=3x+5
Step 2: Subtract 3x from both sides.
3x−4−3x=3x+5−3x
−4=5
Step 3: Add 4 to both sides.
−4+4=5+4
0=9
Answer:
The answer would be 17
Step-by-step explanation:
The answer would be 17 because if you add 12 plus 5 That would be your answer
