please help me !!!!
please can anyone solve this ???​

Answer 1

Answer:

a) |x+y| = |-1/5 + 3/25| = |-5 + 3/25| = |-2/25| = 2/25

|x| + |y| = |-1/5| + |3/25| = 1/5 + 3/25 = 5 + 3/25 = 8/25

∴ |x+y| < |x| + |y|

b) |x+y| = |-7/2 -13/12| = |-42-13/12| = |-55/12| = 55/12

|x| + |y| = |-7/2| + |-13/12| = 7/2 + 13/12 = 42+13/12 = 55/12

∴ |x+y| = |x| + |y|
