JJ -------11.20 US Sucked
Hi there, I hope I could contribute to this forum with my own jijing, although I screwed up my GMAT test this afternoon here in US.
First, I'd like to thank ya'll, since the Math part has so many JJs that can help us alot! I encountered a bunch of JJs, like 10 or so. However, there are several questions I'd like to tell you here in a bid to thank you for your assistance in turn.
1: How many digits of mn?
a: m has 5 digits
b: n has 10 digits
My answer: E
2:
X: 0, 1, 2, 3, 4
Y: unknown(on the test), -1, -3, -3/2 (or -5/2) I cannot rememer this number
You are asked to provide the equation,
my answer was like: Y=2x-1 or Y=X-1 ...sorry i cannot remember my answer.  (
