Which linear polynomial represents a quantity with an initial value of 120 that decreases by 5 units for every increase of 1 unit in x?

Answer and explanation

Correct answer: \(120-5x\)

In \(120-5x\), the constant term 120 gives the initial value, while the coefficient of x is \(-5\), so the quantity falls by 5 per unit of x. \(120+5x\) represents growth. Exam tip: decay has a negative x-coefficient.
