II. $y^{2} - 18 y + 80 = 0$ , then compare $x$ and $y$ .

Competition practiceQuadratic Comparison

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

Step-by-Step Solution

I:

(x - 4) (x - 7) = 0

, so

x = 4

or 7. II:

(y - 8) (y - 10) = 0

, so

y = 8

or 10. Every

x

is smaller than every

y

, so

x < y

.

Answer: D)

x < y
