I'm assuming you mean 
, not 
, like your prompt suggests.
First, let's figure out what rule we can use. A likely noticeable one is the Power Rule, which says the following:
![\dfrac{d}{dx} [u^a] = a(u)^{a-1} du](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%7D%7Bdx%7D%20%5Bu%5Ea%5D%20%3D%20a%28u%29%5E%7Ba-1%7D%20du)
Applying this, we can solve for the derivative:
While you can simplify the expression to your liking, I believe that this form is not overly complex and will thus leave it as is.
Thus, our answer is:
Answer:
96
Step-by-step explanation:
60/100 x 60 = 96
Answer: Slope is -1
Using the slope formula, we get
m = (y2 - y1)/(x2 - x1)
m = (0 - 4)/(2 - (-2))
m = (0 - 4)/(2 + 2)
m = -4/4
m = -1
What's going on here is that we subtract the y values 0 and 4 to get -4. This means that we dropped 4 units vertically to go from A to B. This is the rise. So rise = -4
The run is 4 because we moved 4 units to the right to go from A to B. This is found algebraically when we subtracted the x coordinates, so 2 - (-2) = 2 + 2 = 4.
Slope = rise/run = -4/4 = -1
You have the correct answer, assuming you wrote -1. I think your teacher just marked it wrong because you forgot to show steps.
Answer:
y=0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2.6y-4/15y+7/6y=7/3y
2.6y-(-)4/15y+7/6y=7/3y
(2.6y-4/15y+7/6y)=7/3y (combine like terms)
7/2y = 7/3y
Step 2: Subtract 7/3y from both sides.
7/2y - 7/3y = 7/3y - 7/3y
7/6y = 0
Step 3: Multiply both sides by 6/7
6/7 . 7/6y = 6/7 . 0
y = 0
