Question

1 f r 2 The additive inverse of 3 is : (a) - 3 (b) o (c) 1 (d) 3 30(-7) is : (a) 7 (b) - 7 co (d) Not defined 1 4 The sum of two integers is zero, if one of them is -9, then other is:​

Answer 1

Answer:

1) (a) - 3

2) (a) 7

3) Other number is x = 9

Step-by-step explanation:

The additive inverse of a number a is the number that, when added to a, yields zero. This number has the opposite sign.

The additive inverse of 3 is (a) - 3

The additive inverse of (-7) is (a) 7

Sum of two integers is 0, if one of them is -9, then other is:​

-9 + x = 0

x = 9 (additive inverse)

Other number is 9
