Final answer:
The compound inequality that represents the phrase 'all real numbers that are less than -3 or greater than or equal to 5' is x < -3 or x ≥ 5.
Step-by-step explanation:
The compound inequality that represents the phrase 'all real numbers that are less than -3 or greater than or equal to 5' is option A) x < -3 or x ≥ 5.
To understand why, we need to break down the phrase:
- 'less than -3' is represented by x < -3
- 'greater than or equal to 5' is represented by x ≥ 5
Using the word 'or' to connect the two inequalities, the compound inequality becomes x < -3 or x ≥ 5.
