Question

1. If x = 1/2and y = -1/2 ,then
(a) x+y> 0 (6) x - y<0.
(c) x-y=1 (d) x + y = 1
​

Answer 1

Answer:

Option (c) is correct

Step-by-step explanation:

$Given \: x = \frac{1}{2},\\y = \frac{-1}{2}$

$i) x+y \\ = \frac{1}{2}+ (\frac{-1}{2})\\=\frac{1}{2}-\frac{1}{2}= 0$

$ii)x-y \\= \frac{1}{2}-(\frac{-1}{2})\\=\frac{1}{2}+ \frac{1}{2}= 1$

Therefore,

Option (c) correct.
