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:
105°
cause You can measure an arc in degrees just like you measure an angle
The geometric mean of 2 & 200 is *(20)*
Start the graph at the <em>y</em>-intercept. At 0 hours, he will make $0, so (0, 0) is the <em>y</em>-intercept. From this point, he makes $8.10 an hour; go up 8.1 for every 1 hour you go over on the graph. The graph is attached.
Answer:
x = 3/7
x = 0.43
Step-by-step explanation:
Make x the subject
x > ×7 > + 4 > -4 = 3
3 > + 4 > -4 > ÷ 7 = x
