What is the solution of the compound inequality 0 < (9 − 3x)/6 ≤ 2?

Answer and explanation

Correct answer: −1 ≤ x < 3

Treat the compound inequality as two conditions that must hold simultaneously. Since 6 is positive, multiply all three parts by 6 without reversing either sign: 0 < 9 − 3x ≤ 12. From 0 < 9 − 3x, subtract 9 to get −9 < −3x, and divide by −3, reversing the sign: x < 3. From 9 − 3x ≤ 12, subtract 9 to get −3x ≤ 3, and divide by −3: x ≥ −1. Combining the conditions gives −1 ≤ x < 3, so option C is correct. The lower endpoint is included because x = −1 makes the fraction 2, while x = 3 is excluded because it makes the fraction 0.
