Show Answer
Answer:
Correct Answer: E
Solution:
- I. $ x^{2}=9 $
$ \Rightarrow $ $ x=\sqrt{9} $
$ \Rightarrow $ $ x=\pm 3 $ II. $ 2y^{2}-19y+44=0 $
$ \Rightarrow $ $ 2y^{2}-11y-8y+44=0 $
$ \Rightarrow $ $ y(2y-11)-4(2y-11)=0 $
$ \Rightarrow $ $ y=4, $ $ 11/2 $
$ \therefore $ Relationship cannot be determined.
