Question

Пусть x= -1/3 и y= 0,5. Найдите значение каждого из выражений : -(x+y) -(x-y) -(-x+y) -(-x-y)

Answer 1

-(х+у) = -((-1/3+1/2)= -(1/6) = -1/6
-(х-у) = -(-1/3-1/2) = -(-5/6) = 5/6
 -(-х+у)= х-у = -1/3-1/2= -5/6
-(-х-у) = х+у = -1/3+1/2 = 1/6

Answer 2

-(-1/3+0,5)= 1/3-0,5=1/3-1/2=2/6-3/6=-1/6
-(-1/3-0,5)=1/3+0,5=1/3+1/2=2/6+3/6=5/6
-(-(-1/3)+0,5)= -(1/3+0,5)= -5/6
-(-(-1/3)-0,5)=-(1/3-0,5)=-(2/6-3/6)=1/6

Answer 3

-(x+y) = -(-1/3 + 0.5) = -(-1/6) = 1/6 -(x-y) = -(-1/3 - 0.5) = -(-4/6) = 2/3 -(-x+y) = -(1/3 + 0.5) = -8/6 = -4/3 -(-x-y) = -(1/3 - 0.5) = -(-2/6) = 1/3

Таким образом, значение каждого из выражений равно: -(x+y) = 1/6 -(x-y) = 2/3 -(-x+y) = -4/3 -(-x-y) = 1/3
