Answer:
- A matches with 5.
- B matches with 3.
- C matches with 2.
- D matches with 6.
- E matches with 4.
- F matches with 1.
Step-by-step explanation:
To find the inverse of a function 
, we let 
and then solve again for y.
For example, using 
, we will let 
, giving 
. This means that 
, and thus 
.
Using similar logic, we see that:
- A matches with 5.
- B matches with 3.
- C matches with 2.
- D matches with 6.
- E matches with 4.
- F matches with 1.

The volume of the 12% salt solution to be added is; 2.5 gallons.
<h3>Ratio and Proportion of Volume</h3>
Let the volume of 12% required be x and the new volume of the mixture be (x+5).
On this note, it follows that;
Hence, -2x = -5
Divide both side by -2;
x = 2.5 gallons.

Answer:
x is any number less than -64; i.e. -66
Step-by-step explanation:
Inequality
3x + 23y - 15 < 0
where point (x,9) satisfies this
Substitute 9 for y
3x + 23(9) - 15 < 0
3x + 207 - 15 < 0
3x + 192 < 0 Take away 192 from both sides
3x < -192 Divide both sides by 3 to isolate x
x < -64
Check:
3(-64) + 23(9) -15 < 0
-192 + 207 - 15 < 0
-192 + 192 < 0
Therefore x must be less that -64 to satisfy the point (x, 9) in this inequality.
