For this case we must find the inverse of the following function:
For this, we follow the steps below:
We change f (x) to y:
We exchange the variables:
We solve for y:
We divide between 8 on both sides of the equation:
We raise both sides of the equation to the square to remove the root:
So, the inverse is:

Option C
The correct answer would be that if Dimitri improves his average by 1, he would have a 13.375 rebound per game average.
Although they don't tell you how many games he place, we can still solve. This is because we are adding an average to an average and therefore don't need to know totals.
12.375 + 1 = 13.375
21% were absent, if you divide 146 by 680 and multiply by 100, then round to the nearest whole number, you get 21
Answer:
1 hotdog is $3.5.
1 drink is $2.
Step-by-step explanation:
18.50= 3x+4y(times 5)
25.50=5x+4y(times -3)
92.5=15x+20x
-76.5=-15x+-12y
16=-8y
2=y
18.50=3x+4(2)
10.50=3x+8
10.50=3x
3.5=x
