graph the compound inequality on the number line. \n$x < -1$ or $x > 8$
graph the compound inequality on the number line. \n$x < -1$ or $x > 8$
Answer
Explanation:
Step1: Mark boundary for x < -1
Use an open circle at $x=-1$ (since -1 is not included), then draw an arrow pointing left from this circle to represent all values less than -1.
Step2: Mark boundary for x > 8
Use an open circle at $x=8$ (since 8 is not included), then draw an arrow pointing right from this circle to represent all values greater than 8.
Answer:
- On the number line:
- Place an open circle at $-1$ and shade/arrow all values to the left of $-1$.
- Place an open circle at $8$ and shade/arrow all values to the right of $8$.
