Question

Comparati numerele intregi x si y, stiind ca : x+y<0, x·y>0 si /x/ < /y/

Answer 1

$x+y\ \textless \ 0 \\ x*y\ \textgreater \ 0 \\ |x|\ \textless \ |y| \\ Inlocuim \ cu \ orice \ numar \ ce \ apartine \ Z: \\ x=-2, \ y=-5, \ deoarece \ |-2|\ \textless \ |-5| \\ -2+(-5)=-7, \ deci \ -7\ \textless \ 0, \ (A) \\ -2*(-5)=10, \ deci \ 10\ \textgreater \ 0, \ (A) \\ Rezulta \ ca \ \boxed{x\ \textless \ y}$
