Two equations are given. Solve both and choose the correct relation. I. $x^{2} - 9 x + 20 = 0$
II. $y^{2} - 11 y + 30 = 0$

Competition practiceQuadratic Comparison

A $x$ ≥ $y$
B $x > y$
C $x$ ≤ $y$
D $x < y$

Step-by-Step Solution

x = 4

or 5 and

y = 5

or 6, so the largest

x

equals the smallest

y

, giving

x

≤

y

.

Answer: C)
