Which of the following inequalities represents "x is less than or equal to 10"?

Answer explanation

The inequality "x is less than or equal to 10" is correctly represented by x ≤ 10. This indicates that x can be any value up to and including 10, making the correct choice x ≤ 10.

Answer explanation

To solve the inequality 3x - 5 > 7, add 5 to both sides to get 3x > 12. Then, divide by 3 to find x > 4. Thus, the solution set is x > 4, which matches the correct answer.

Answer explanation

To solve the inequality 5x + 4 < 19, subtract 4 from both sides to get 5x < 15. Then, divide by 5 to find x < 3. Thus, the correct choice is x < 3.

Answer explanation

To solve the inequality x - 7 ≥ 2, add 7 to both sides: x ≥ 9. Thus, the solution for x is x ≥ 9, which corresponds to the answer choice x ≥ 9.

Answer explanation

To solve the inequality 4x - 1 ≤ 15, add 1 to both sides: 4x ≤ 16. Then, divide by 4: x ≤ 4. Thus, the correct answer is x ≤ 4.

Answer explanation

To solve the inequality \(2x + 6 < 14\), subtract 6 from both sides to get \(2x < 8\). Then, divide by 2 to find \(x < 4\). Thus, the correct answer is \(x < 4\).

Answer explanation

To solve the inequality -2x + 3 ≤ 7, subtract 3 from both sides to get -2x ≤ 4. Then, divide by -2, reversing the inequality sign, resulting in x ≤ 2. Thus, the correct answer is x ≤ 2.
