Answer:
f-1(x) = (x-8)/2
Step-by-step explanation:
f(x) = 2x+ 8
y = 2x + 8
replacing y and x
x = 2y + 8
2y = x- 8
y =( x-8)/2
f-1 (x) =( x-8)/2

Step-by-step explanation:
The marginal benefit of an article,
is calculated as:

Where
is the change in the total benefit of the article, and
is the change in the units of the article.
If we want to know the marginal benefit of watching the 3rd game, we need to use the information of total benefit of watching 2 games and 3 games.
In this case, the total benefit of watching 2 games is 120 and the total benefit of watching 3 games is 125, so
and
are equal to:


Then, the marginal benefit of watching the third game is:

13d-(-9d-4)
Transfer minus sign to all numbers in parenthesis. = 13d +9d +4 =
Answer: 22d+4
<span>If it decreases by 12 percent, you do 19,200x.12 which is 2,304. You subtract that from 19,200 which is 16,896. You multiply that by .12 which is 2,027.52 and subtract that from 16,896 which is 14,868.42. You do that three more times and there's your answer.
