If (c-5)(y+2) = 0 which of the following must be true?	Choose the correct answer
A) c = y  B) c > y  C) c < y  D) cy = -10  E) None of the above
From (c-5)(y+2) = 0 it follows that either c=5 or y=-2.   (A) c = y --&gt; not necessarily true. Consider c=5 and y=0.   (B) c &gt; y --&gt; not necessarily true. Consider c=5 and y=10.   (C) c &lt; y --&gt; not necessarily true. Consider c=5 and y=0.   (D) cy = -10 --&gt; not necessarily true. Consider c=5 and y=0.   Thus, none of the statements must be true.   Answer: None of the above.
