hartnn (hartnn):

(x-y)<(x+y)

OpenStudy (anonymous):

x-y < x+y x-x<y+y y>0

OpenStudy (anonymous):

i hope thats right...

OpenStudy (anonymous):

ahh

OpenStudy (anonymous):

Actually it should be x>0 and y>0

OpenStudy (anonymous):

2-2 is less than 2+2

OpenStudy (anonymous):

So both numbers have to be positive?

OpenStudy (anonymous):

YEP

OpenStudy (anonymous):

wait

OpenStudy (anonymous):

nopes.... @sauravshakya x can be of any number x belongs to R so

OpenStudy (anonymous):

answer booklet says B

OpenStudy (anonymous):

What about -2 and 2 then

OpenStudy (anonymous):

At least one of the numbers is positive

OpenStudy (anonymous):

Difference is 4 and sum is 0

OpenStudy (anonymous):

\[\forall X \in R and Y>0 x-y<x+y\]

OpenStudy (anonymous):

2+2 is less than 2-2

OpenStudy (anonymous):

ehh

OpenStudy (anonymous):

At least one of the numbers is positive?

OpenStudy (anonymous):

but the difference there is greater than the sum

OpenStudy (anonymous):

so how can that be true?

OpenStudy (anonymous):

2+2=4 for difference

OpenStudy (anonymous):

2-2=0 for sum

OpenStudy (anonymous):

whats the hell is 2+2 < 2-2 ???

OpenStudy (anonymous):

4 is less than 0?

OpenStudy (anonymous):

wah?

OpenStudy (anonymous):

then the difference=4 and sum=0

OpenStudy (anonymous):

that does that make sense

OpenStudy (anonymous):
