How did you come up with x-y = 16 from the question?
Hi Gogetter08,
How did you come up with x-y = 16 without loss of generality from the equation |x| + |y| = 32.
Please explain.
Appreciate your feedback.
Thanks

In xy plane y=3x+2 contain (r,s)
In xy plane y=3x+2 contain (r,s) 1) (3r+2-s)(4r+9-s)=0 2) (4r-6-s)(3r+2-s)=0 I think each statement alone is sufficent..But it is wrong! I think tht the answer should be "C" This is because when you consider statement 1 alone, there are 2 solutions: either s = 3r + 2 or s = 4r + 9. So, sta...

Once we realize that we can look at the 2 alternatives. A. x <3> 3 or x < 3. So we can not say for sure whether x <= 3. Insuff...

Tricky Algebra Data sufficiency problem
If b, c, and d are constants and x^2 + bx + c = (x + d)^2 for all values of x, what is the value of c? (A) d = 3 (B) b = 6 Resolving the equation produces bx +c = 2dx + d^2 for all values of x. Analysis 1. If we now conclude that 2d = b and c = d^2. So A is sufficient because c = d^2 = 9. B is suffi...
