Question 9 • FL-1200370-Algebra 1-A Semester 1

What is a correct first step in solving the inequality –4(3 – 5x)≥ –6x + 9?

Answer
A
–12 – 20x ≤ –6x + 9
B
–12 – 20x ≥ –6x + 9
C
–12 + 20x ≤ –6x + 9
D
–12 + 20x ≥ –6x + 9

Explanation

Distribute –4 to both terms inside the parentheses: (–4)(3) = –12 and (–4)(–5x) = +20x. The inequality sign stays ≥ because we have not multiplied or divided both sides by a negative number. The correct first step is –12 + 20x ≥ –6x + 9, choice D.
