-2/2 and -2/-4 hoppeee it helps
752/12 = 62.66 and since she can't sell a portion of a 12 pack, she sold 62 whole packages and had 2/3 of one remaining, 2/3 of 12 is 8 remaining.
Hello :
2x² = 2
x²=1
x²-1=0
(x-1)(x+1) = 0
x-1=0 or x+1=0
x=1 or x= -1...(answer : <span>B. There are two solutions: -1 and 1 )</span>
Replace,
x = y
Or
x = f(x)
then us stay:
x = 5y + 12
Isolate 5y
5y = x - 12
Dividing both the sides by 5
y = x/5 - 12/5
Then, replace y = f^-(x)
f^-(x) = x/5 - 12/5
Hope this helps
Answer:

Step-by-step explanation:
You need to apply the chain rule here.
There are few other requirements:
You will need to know how to differentiate
.
You will need to know how to differentiate polynomials as well.
So here are some rules we will be applying:
Assume 




Those appear to be really all we need.
Let's do it:






I tried to be very clear of how I used the rules I mentioned but all you have to do for derivative of natural log is derivative of inside over the inside.
Your answer is
.
