2(b-5)+7b-4
Solve 2(b-5) to get 2b-10
Combine your like terms 2b-10+7b-4
Solve 2b+7b to get 9b
Solve -10+(-4) to get -14
So your answer is
9b-14
Given that 
, we have 
, so that
Take the derivative and find the critical points of 
:
Take the second derivative and evaluate it at the critical point:
Since 
is positive for all 
, the critical point is a minimum.
At the critical point, we get the minimum value 
.
Answer:
x=26
Step-by-step explanation:
first rewrite the problem since u know that G(x)=-48
-48=-3/2x-9
second you want to add the 9 to -48 which gives u -39
-39=-3/2x
third you want to times the reciprocal so it would be
-2/3 times -39/1
u can cross out the negatives and turn them into a positive
fourth you can cross cancel 3 and 39 which now the problem looks like this
2/1 times 13/1
which you would times 2 and 13 which your answer would be
26
The first step is to find out the value of one diaper for each equation
39.98/216 = 0.18
Therefore one diaper is for 0.18 cents
24.99/88 = 0.28
Therefore one diaper is for 0.28 cents
At the end the first deal is better
