Important Information:
A Book Has 12 Chapters.
The Mean length of the chapters is 40 pages.
Question to Answer:
How many total pages are there in the 12 chapters?
Explanation/Solution:
Let's assume that the total number of pages in the book is "x" pages.
To find the mean (average) we divide the total "x" by 12 because there are 12 chapters in the book, which would equal to 40.
=40
Multiply both sides by 12...
x = 480
Hence, The total number of pages in the 12 chapters is 480.

Step-by-step explanation:
I'm seeing that f(x) is
What you do to find an inverse is switch the x and y coordinates and then solve for the new y. Switching the x and y gives us:
Now we have to solve for the new y. Begin by muliplying both sides by 6 to get:
6x = 3y - 2 and
6x + 2 = 3y so
2x + 2/3 = y
