Question 7 • CUSD Advanced Math A (5.0)

What is the solution set to 8(2x – 3) ≤ 20 – 4x?

Answer
A
(–∞,∞)
B
(–∞, 2]
C
(0, 20)
D
[2, ∞)

Explanation

Distribute first: 8(2x − 3) ≤ 20 − 4x becomes 16x − 24 ≤ 20 − 4x. Add 4x and 24 to both sides to get 20x ≤ 44, so x ≤ 44/20 = 11/5. Wait—this is not the endpoint shown in choice B, so none of the listed choices matches the inequality as written.
