Match each inequality on the left with its correct solution on the right.
Some answer choices on the right will be used more than once.

Sure! Let's match each inequality with its correct solution step by step.

1. Inequality: [tex]\(4x + 1 > 9\)[/tex] and [tex]\(-6x - 2 > 10\)[/tex]
- To solve [tex]\(4x + 1 > 9\)[/tex]:
[tex]\[ 4x + 1 > 9 \][/tex]
[tex]\[ 4x > 8 \][/tex]
[tex]\[ x > 2 \][/tex]
- To solve [tex]\(-6x - 2 > 10\)[/tex]:
[tex]\[ -6x - 2 > 10 \][/tex]
[tex]\[ -6x > 12 \][/tex]
[tex]\[ x < -2 \][/tex]
- Since [tex]\( x > 2 \)[/tex] and [tex]\( x < -2 \)[/tex] cannot be true simultaneously, there is no solution.

Solution: no solution

2. Inequality: [tex]\(|-3x| < 6\)[/tex]
- Since [tex]\(|-3x|\)[/tex] is the absolute value of [tex]\(-3x\)[/tex], it means:
[tex]\[ |-3x| < 6 \][/tex]
- This can be split into two parts:
[tex]\[ -3x < 6 \][/tex]
[tex]\[ x > -2 \][/tex]
[tex]\[ 3x < 6 \][/tex]
[tex]\[ x < 2 \][/tex]
- Combining these two parts, we get:
[tex]\[ -2 < x < 2 \][/tex]

Solution: [tex]\(-2 < x < 2\)[/tex]

3. Inequality: [tex]\(|3x| + 5 < 4\)[/tex]
- To solve [tex]\(|3x| + 5 < 4\)[/tex], we first isolate the absolute value:
[tex]\[ |3x| + 5 < 4 \][/tex]
[tex]\[ |3x| < -1 \][/tex]
- Since an absolute value cannot be negative, there is no solution.

Solution: no solution

4. Inequality: [tex]\(|x + 2| > 1\)[/tex]
- Since [tex]\(|x+2|\)[/tex] is the absolute value, it gives us two cases:
[tex]\[ x+2 > 1 \text{ or } x+2 < -1 \][/tex]
- For [tex]\( x + 2 > 1 \)[/tex]:
[tex]\[ x > -1 \][/tex]
- For [tex]\( x + 2 < -1 \)[/tex]:
[tex]\[ x < -3 \][/tex]
- Combining these two parts, we get:
[tex]\[ x > -1 \text{ or } x < -3 \][/tex]

Solution: [tex]\(x > -1 \text{ or } x < -3\)[/tex]

Therefore, the matches are:

- [tex]\(4x + 1 > 9\)[/tex] and [tex]\(-6x - 2 > 10\)[/tex] → no solution
- [tex]\(|-3x| < 6\)[/tex] → [tex]\(-2 < x < 2\)[/tex]
- [tex]\(|3x| + 5 < 4\)[/tex] → no solution
- [tex]\(|x + 2| > 1\)[/tex] → [tex]\(x > -1 \text{ or } x < -3\)[/tex]
