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:

\({x:1 \leq x < 3}\)
