Which is the negation of the statement x ≤ −3?

Answer and explanation

Correct answer: x > −3

The negation of an inequality must describe exactly the values that do not satisfy the original statement. The statement x ≤ −3 includes every value less than or equal to −3. Its complement on the real number line consists of values strictly greater than −3, so the negation is x > −3, option A. Notice that the equality case is important: x = −3 belongs to the original statement and therefore cannot belong to its negation. Option B incorrectly includes the boundary value, while option C describes only part of the original set rather than its complement. Option D is only one value and does not represent all excluded values. Thus A is the precise logical negation.
