Thanks a ton.. been lukin for a correct technique for ineq..
how does that address the question stems individually? You skipped straight to the answer of E which I understand when combining both questions, but I do not understand the question stems separately.
That was a great tip! thanks
Couldn't you skip a step? Once you know y plug it in to the first statement and get x>-3 ?
addmore on coordinate geometry
I finally understand this concept. Thank you very much!
At 3:05, I don't understand… how did you get y>2? If you replace "y" by 2.1 then 2*2.1= 4.2 and therefore does not seems to be greater than 7 doesn't "y" has to be between 3.5 and 5 ? I'm not sure…
Thanks you very much for the tip!
As with the above logic,it should hold true that the answer to such question will be C or E ,hence we can directly eliminate A,B,D…Does that hold tru for all the cases?
So there are people who try to get into a MBA or such with a GMAT and can't do 10th grade math. Okay. I am excited for this.
Excellent video! Just one query: For the Range problem, are you implying that the answer will always be D or E ?
A good one! Awesome, thanks :)
Is anyone else seeing that he's dipping in the video?
If Y must be positive, and X cannot be either. It would be logically flawed to say that X can be negative if Y must be positive, because X multiplied by Y must be greater then 0. If Y is positive, and x is negative the answer is inherently negative and therefor less then 0.
Thoughts? Not sure if this was supposed to work out this way for your example but I get the concept and strategy thanks.
