Question

Solutions of the inequalities comprising a system in variable x are represented on number lines as given below, then ______.

Options

• x ∈ (–`oo`, –4] ∪ [3, `oo)`

• x ∈ [–3, 1]

• x ∈ (–`oo`, –4) ∪ [3, `oo`)

• x ∈ [–4, 3]

Answer 1

Solutions of the inequalities comprising a system in variable x are represented on number lines as given below, then x ∈ (–∞, –4] ∪ [3, ∞).

Explanation:

x ∈ (–∞, –4] ∪ [3, ∞) is the correct choice. Common solution of the inequalities is from –∞ to –4 and 3 to ∞.
