The solution set in interval notation is [–11, 7).
Solución
We start with the compound inequality:
–9 ≤ x + 2 < 9
Step 1: Subtract 2 from all parts to isolate x:
–9 – 2 ≤ x + 2 – 2 < 9 – 2
–11 ≤ x < 7
Step 2: Write the solution set in interval notation:
The solution set is [–11, 7).
Step 3: Graph the solution:
• Place a closed (filled) circle at –11.
• Place an open circle at 7.
• Shade the line between –11 and 7.
This completes the isolation and representation of x.

Simplifique esta solución Mind Expander
To isolate \( x \) in the compound inequality \( -9 \leq x+2 < 9 \), we first subtract 2 from all parts of the inequality: \[ -9 - 2 \leq x + 2 - 2 < 9 - 2 \] This simplifies to: \[ -11 \leq x < 7 \] So the solution set in interval notation is \( [-11, 7) \). For the graph of the solution, you would represent it on a number line where the point -11 is included (closed dot) and the point 7 is not included (open dot).
