I. \(x^2 - 27x + 162 = 0\) II. \(y^2 + 6y - 135 = 0\)

1. x > y
2. x ≥ y
3. y > x
4. y ≥ x

Correct answer: x ≥ y

Solution

The first equation factors as \((x-9)(x-18)=0\), so \(x=9\) or \(18\). The second factors as \((y+15)(y-9)=0\), so \(y=-15\) or \(9\). Hence \(x\ge y\) is the best matching relation.
