I. $x^{2}=144$
II. $y^{2}-24 y+144=0$
(1) $x \leq y$
(2) $x \geq y$
(3) relationship between $x$ and $y$ cannot be determined
(4) $ x<y $
(5) $ x>y $
Show Answer
Correct Answer: 2.(1)
Solution: (1) I. $x^{2}=144$
$\Rightarrow x=\sqrt{144}= \pm 12$
II. $y^{2}-24 y+144=0$
$\Rightarrow(y-12)^{2}=0$
$\Rightarrow y-12=0 \Rightarrow y=12$
Clearly, $x \leq y$
