If \(b\ge 10\), what inequality is obtained by subtracting \(6\) from both sides?

Answer and explanation

Correct answer: \(b-6\ge 4\)

Subtracting the same number, \(6\), from both sides of \(b\ge 10\) gives \(b-6\ge 10-6=4\). The inequality sign does not reverse when the same number is added or subtracted from both sides. Thus, A is correct; option B incorrectly reverses the sign. Exam tip: the sign reverses only when both sides are multiplied or divided by a negative number.
