If \(2x+5\) is not positive, which of the following inequalities for \(x\) is correct?

Answer and explanation

Correct answer: \(x\leq -\frac{5}{2}\)

‘Not positive’ means the expression can be zero or negative, so \(2x+5\leq 0\). Subtracting 5 from both sides gives \(2x\leq -5\), and dividing by 2 gives \(x\leq -\frac{5}{2}\). Therefore, option D is correct. Option C incorrectly uses \(<\) and excludes \(x=-\frac{5}{2}\), even though the expression equals zero at that value and is therefore not positive. Exam tip: ‘not positive’ includes zero, whereas ‘negative’ excludes zero.
