Answer:
-3
Step-by-step explanation:
This is because your questions is in an y=mx+b form therefore b is the y-intercept and in this equation -3 would be b therefore that the is the y-intercept
Using derivatives, it is found that the slope of the line tangent to the graph of y at x = 1 is of 5.
The equation is:

The slope of the line tangent to the graph of y at x = 1 is
.
Applying the quotient rule, we have that:
![y^{\prime}(x) = \frac{[9x^2]^{\prime}(x + 2) - [x + 2]^{\prime}(9x^2)}{(x + 2)^2}](https://tex.z-dn.net/?f=y%5E%7B%5Cprime%7D%28x%29%20%3D%20%5Cfrac%7B%5B9x%5E2%5D%5E%7B%5Cprime%7D%28x%20%2B%202%29%20-%20%5Bx%20%2B%202%5D%5E%7B%5Cprime%7D%289x%5E2%29%7D%7B%28x%20%2B%202%29%5E2%7D)


Then, when x = 1:

The slope of the line tangent to the graph of y at x = 1 is of 5.

Lets say we represent the amount of time she could ski.
So it would be x = the amount of time she skis
And 5x would represent how long it took her to climb
and she took 9 minutes to climb.
So what we would do first is put it in a equation like this
x + 5x = 9
Now we have 6x = 9
Divide 9 by 6x, and we get x = 15
So multiply 1.5 by 5 and the answer would be 7.5
Hopefully this helped. :)
Answer:
Step-by-step explanation:
wx+yz=uv-2wx
uv = wx + yz + 2wx
u = ( wx + yz + 2wx ) / v
hope it helps :)
