To solve the compound inequality \(-3 \leq 2x - 5 < 1\), we will tackle it in two parts.
1. **Solve the left part:**
\(-3 \leq 2x - 5\)
Add 5 to both sides:
\[
2 \leq 2x
\]
Divide by 2:
\[
1 \leq x \quad \text{or} \quad x \geq 1
\]
2. **Solve the right part:**
\(2x - 5 < 1\)
Add 5 to both sides:
\[
2x < 6
\]
Divide by 2:
\[
x < 3
\]
Now we combine these two results:
\[
1 \leq x < 3
\]
In set notation, this is expressed as:
\[
\{x: 1 \leq x < 3\}
\]
So the correct response is:
\(\{x:1 \leq x < 3\}\)
