Final answer:
The value of x is less than or equal to 2 in interval notation. The correct answer is C) 3.
Step-by-step explanation:
The inequality given is x ≤ 2. In interval notation, this can be represented as (−∞, 2] which means that the value of x can be any number less than or equal to 2. Option A, which is 5, is greater than 2, so it does not satisfy the inequality. Option B, which is 7, is also greater than 2 and does not satisfy the inequality. Option C, which is 3, is equal to 2 and it satisfies the inequality. Option D, which is 9, is greater than 2 and does not satisfy the inequality. Therefore, the correct answer is C) 3.
