X = 20
If you multiply both sides by 5 to get rid of the fraction ( x - 60 = -40 ) the answer would become clear.
Answer:
30 mL
Step-by-step explanation:
Mr. Allen needs 100 mL of a solution that is
- 30% vinegar,
- 15% lemon juice,
- 55% water.
Thus, there are
of vinegar,
of lemon juice,
of water.
Given:
The function is:

To find:
The steps of finding the inverse function
.
Solution:
We have,

The steps of finding the inverse function are:
Step 1: Substitute
.

Step 2: Interchange x and y.

Step 3: Taking square on both sides, we get

Step 4: Adding 21 on both sides, we get

Step 5: Divide both sides by 7.

Step 6: Substitute
.
, where
.
Therefore, the inverse of the given function is
and the arrangement of steps is shown above.
