Answer
The solution set is \( (0, 5] \).
Solution
1. Start with the compound inequality:
\[
-1 < 2x - 1 \leq 9
\]
2. Add \(1\) to all three parts of the inequality:
\[
-1 + 1 < 2x - 1 + 1 \leq 9 + 1
\]
which simplifies to:
\[
0 < 2x \leq 10
\]
3. Divide each part by \(2\) (since \(2\) is positive, the direction of the inequalities remains unchanged):
\[
\frac{0}{2} < \frac{2x}{2} \leq \frac{10}{2}
\]
simplifying to:
\[
0 < x \leq 5
\]
4. In interval notation, the solution set is:
\[
(0, 5]
\]
Answer: A. The solution set is \( (0, 5] \).

To solve the compound inequality \(-1 < 2x - 1 \leq 9\), we can split it into two parts. First, solve \(-1 < 2x - 1\): 1. Add 1 to both sides: \(0 < 2x\). 2. Divide by 2: \(0 < x\) or \(x > 0\). Next, solve \(2x - 1 \leq 9\): 1. Add 1 to both sides: \(2x \leq 10\). 2. Divide by 2: \(x \leq 5\). Combining these results, we have \(0 < x \leq 5\). In interval notation, the solution set is \((0, 5]\). The correct choice is A. The solution set is \((0, 5]\).
