Question

Identify the solution set of the inequality using the given replacement set x < –2; {–5, –2.6, –2, –0.8, 1, 1.5}. A. {–5, –2.6} B. {–5, –2.6, –2} C. { –2, –0.8, 1, 1.5} D. {–0.8, 1, 1.5}

Answer 1

If x < - 2 and x ∈ { - 5, - 2.6, - 2, - 0.8, 1, 1.5 }
- 5 < - 2 and - 2.6 < - 2
The solution set is:
A ) { - 5 , - 2.6  }

Answer 2

If x < - 2 and x ∈ { - 5, - 2.6, - 2, - 0.8, 1, 1.5 }

- 5 < - 2 and - 2.6 < - 2

The solution set is:

A ) { - 5 , - 2.6  }
