I need to know if i got this math question wrong or right. Lobster test

<p>THe question was</p>

<p>there is a line with points x y z on it</p>

<p>and it had 3 choices of</p>

<p>I
II
III </p>

<p>I put II, III wasnt sure about I. Is anyone certain it was I, II, III?</p>

<p>this breaks me at 1 or 2 wrong. Please help</p>

<p>it's all three, certain</p>

<p>plugged in various number to prove them all</p>

<p>oh well 2 wrong. lets hope for the best</p>

<p>btw do you know the choice for part I. Was it XY < 0 XY > 0</p>

<p>YZ < 0 or YZ > 0</p>

<p>and it would help if you knew the specific question so i can figure out where i made the mistake</p>

<p>It was yz>0, and the question was "which of the must be correct." Don't remember the other choices, but I said all of them were correct.</p>

<p>what did it say xyz had to be?</p>

<p>bump ^^^^^^^^</p>

<p>It said xyz had to be a negative odd integer, and I just found out all the choices:</p>

<p>I. x, y, and z are all odd
II. x<0
III. yz>0</p>

<p>It's all three for sure. Go look at the math section thread.</p>

<p>AIYA I remember this question. I totally forgot about the line, so at first I was like uhmm o.o;; I only? And then when i came back to check I finally noticed that there was X Y Z on a line. And that showed why 2 and 3 are correct. lol XD</p>

<p>was 0(zero) b/t any letter?...cuz somehow( i'm not sure though)...i remember thinking something like....since 0 can be between y and z, yz can be negative......i guess i messed up...:(</p>

<p>oo shoot...now i get it...if 0 is b/t y and z...then y and x are both negative which makes a positive which means i got that one wrong:(</p>

<p>yeah, I got all three after much pontification.</p>

<p>lets hope I erased the other two answers I put down first thoroughly enough for them not to screw it... is something like a minutes worth of effort of erasing generally enough?</p>
