It is determined by the graph and what it is.
Step-by-step explanation:
Answer:
He sells 8 CDs and 12 DVDs.
Step-by-step explanation:
In order to solve this, we have to set up a system of equations. We'll let x equal the amount of CDs and y equal the amount of DVDs. First, we'll set up an equation for the total number of items sold.
CDs + DVDs = 20 items
x + y = 20
Now we can set up one for amount of money made.
$9 for every CD + $11 for every DVD = $204
9x + 11y = 204.
Now that we have 2 equations we can solve. To do so, we'll multiply the first equation by -9 and then add them together.
-9x - 9y = -180
9x + 11y = 204
-------------------
2y = 24
y = 12
Now that we have the y value, we can find the x value by plugging into either equation.
x + y = 20
x + 12 = 20
x = 8
F(x) = [2x - 1 - (x-1) in (x - 1)] / [ 1 - in(x-1)]^2
