Question

graph the compound inequality on the number line. x≤ - 7 or x≥8

Explanation:

Step1: Mark -7 on number line

Put a closed circle at -7 (since $x\leq - 7$ includes -7). Then draw a line to the left to represent all values less than or equal to -7.

Step2: Mark 8 on number line

Put a closed circle at 8 (since $x\geq8$ includes 8). Then draw a line to the right to represent all values greater than or equal to 8.

Answer:

On the number - line, there is a closed circle at -7 with a line extending to the left, and a closed circle at 8 with a line extending to the right.
