x < 17
Explanation: Subtract 5: x > 7
Question 2 of 10
medium
Solve: 3x ≤ 15
x ≤ 5
x ≥ 5

Question 3 of 10
medium
When dividing by a negative number, the inequality sign:
Stays same
Flips
Becomes equals
Disappears
Explanation: Multiplying/dividing by negative reverses the sign
Question 4 of 10
medium
The graph of x ≥ 2 has:
Open circle at 2, arrow left
Open circle at 2, arrow right
Closed circle at 2, arrow left
Closed circle at 2, arrow right
Explanation: ≥ means closed circle, arrow right (greater)
Question 5 of 10
medium
Solve: 4x − 7 > 2x + 5
x > 6
x < 6
x > 2
x < 2
Explanation: 4x−2x > 5+7 → 2x > 12 → x > 6

Open circle at -1, arrow left
Open circle at -1, arrow right
Closed circle at -1, arrow left
Closed circle at -1, arrow right
Explanation: < means open circle, arrow left
Question 7 of 10
medium
Solve: −2x ≥ 10
x ≥ −5
x ≤ −5
x ≥ 5
x ≤ 5
Explanation: Divide by −2 (flip sign): x ≤ −5
Question 8 of 10
medium
The compound inequality 2 < x < 5 means:
x > 2 and x < 5
x > 2 or x < 5
x > 5 and x < 2
x > 5 or x < 2
Explanation: "And" means x between 2 and 5
Question 9 of 10
medium
Solve: 5(x − 3) ≤ 2x + 6
x ≤ 7
x ≥ 7
x ≤ −7
x ≥ −7
Explanation: 5x−15 ≤ 2x+6 → 3x ≤ 21 → x ≤ 7
