Question

Solve the following compound inequality.​

Answer 1

C

Explanation:

Given

5x + 7 ≤ - 3 or 3x - 4 ≥ 11

Solve the inequalities either side of the or

5x + 7 ≤ - 3 ( subtract 7 from both sides )

5x ≤ - 10 ( divide both sides by 5 )

x ≤ - 2

or

3x - 4 ≥ 11 ( add 4 to both sides )

3x ≥ 15 ( divide both sides by 3 )

x ≥ 5

Solution is x ≤ - 2 or x ≥ 5 → C
