The image shows a set of rational inequalities labeled as "SEATWORK No. 10 (Pairing)." The goal is to solve each of the following inequalities:

a. \( \frac{1}{2x} - 2 > 0 \)

b. \( \frac{x-3}{x+1} \leq 0 \)

c. \( \frac{2}{x-4} + 5 < 0 \)

d. \( \frac{x+2}{3x+2} - 3 \leq 0 \)

e. \( \frac{x-1}{x+1} \geq 2 \)

### Let's go through each inequality step by step.

---

### a. \( \frac{1}{2x} - 2 > 0 \)

1. Isolate the rational expression:
   \[
   \frac{1}{2x} > 2
   \]
   
2. Multiply both sides by \(2x\) (note that \(x \neq 0\)):
   \[
   1 > 4x
   \]
   
3. Solve for \(x\):
   \[
   x < \frac{1}{4}
   \]

Thus, the solution for inequality (a) is \(x < \frac{1}{4}\), excluding \(x = 0\).

---

### b. \( \frac{x-3}{x+1} \leq 0 \)

1. Set up the critical points by solving where the numerator and denominator are zero:
   - \(x - 3 = 0 \Rightarrow x = 3\)
   - \(x + 1 = 0 \Rightarrow x = -1\)

2. Determine the intervals:
   - \( (-\infty, -1) \), \( (-1, 3) \), and \( (3, \infty) \)

3. Check the sign of the expression in each interval. We want where the expression is less than or equal to zero. The expression will be zero at \(x = 3\).

The solution is \( -1 < x \leq 3 \).

---

### c. \( \frac{2}{x-4} + 5 < 0 \)

1. Isolate the rational expression:
   \[
   \frac{2}{x-4} < -5
   \]

2. Multiply both sides by \(x - 4\) (note \(x \neq 4\)) and solve:
   \[
   2 < -5(x - 4)
   \]

   Simplifying:
   \[
   2 < -5x + 20
   \]
   \[
   5x < 18
   \]
   \[
   x > \frac{18}{5}
   \]

Thus, \(x > \frac{18}{5}\), excluding \(x = 4\).

---

### d. \( \frac{x+2}{3x+2} - 3 \leq 0 \)

1. Isolate the rational expression:
   \[
   \frac{x+2}{3x+2} \leq 3
   \]

2. Multiply both sides by \(3x + 2\), considering where \(3x + 2 = 0\):
   \[
   \frac{x+2}{3x+2} \leq 3
   \]
   Continue solving this inequality.

### Here are five related questions:

1. How do you solve rational inequalities involving multiple terms?
2. What are critical points, and how do they help in solving inequalities?
3. Can you explain how multiplying by a variable expression affects inequalities?
4. How can we check the sign of an inequality over different intervals?
5. What does it mean to exclude values that make the denominator zero in rational inequalities?

### Tip:
Always check the domain of rational inequalities by identifying where the denominator is zero to avoid undefined expressions.

Solve the given rational inequalities:

a. 1/(2x) - 2 > 0
b. (x - 3)/(x + 1) <= 0
c. 2/(x - 4) + 5 < 0
d. (x + 2)/(3x + 2) - 3 <= 0
e. (x - 1)/(x + 1) >= 2
