Solving Compound Inequalities

Question 1 • 4413VA ALGEBRA 3 SEM A

Solve 2 ≤ 2x + 4 < 10 for x.

Answer
A
–1 ≤ x < 3
B
1 < x < 3
C
–1 < x < 3
D
1 ≤ x < 3

Explanation

Subtract 4 from all three parts of the inequality: −2 ≤ 2x < 6. Divide all three parts by 2, keeping the inequality signs in the same direction, to get −1 ≤ x < 3. This matches choice A, “−1 ≤ x < 3.”
