If x ≥ −5 and x < 2 are shown together on a number line, what is the solution set?

Answer and explanation

Correct answer: [−5, 2)

The governing concept is the intersection of two inequalities: a value must satisfy both conditions at the same time. The inequality x ≥ −5 includes −5, so the left endpoint is marked with a closed bracket. The inequality x < 2 excludes 2, so the right endpoint is marked with an open bracket. Combining the common values gives −5 ≤ x < 2, which is written in interval notation as [−5, 2). Therefore, option A is correct. Option B reverses the inclusion signs, while options C and D ignore one of the two restrictions and extend too far along the number line.
