<u><em>Answer:</em></u>
Each shelf can hold 20 boxes of cereal.
<u><em>Step-by-step explanation:</em></u>
Start with 80 boxes of cereal: (80)
There are 4 shelves for each box of cereal: (x/4)
Thus, we get the expression: 80/4=
(You may want to simplify this; giving you the answer of 20.)
Answer:
<em>Thus, f and g are inverse functions</em>
Step-by-step explanation:
<u>Inverse Functions</u>
If two functions f(x) and g(x) are inverses, then it follows that:

Or:

We are given


Let's test if they are inverse functions:

Simplifying:

Now find:

Operating:

Thus, f and g are inverse functions
864=800+60+4 800 in the hundreds place 60 in the tens place and 4 in the ones place
20÷10= 2
50÷10= 5
ratio is2:5
