Question

What must be true about two integers that combine to equal zero

Answer 1

they have to have the same absolute value and one is negative and the other is positive

Answer 2

Answer:  The required TRUE statement is

if two integers combine to equal zero, then they are additive inverses of one another.

Step-by-step explanation:  We are given the state a true statement about two integers that combine to equal to zero.

Let a and b be the two integers. Then, according to the given information, we have

$a+b=0\\\\\Rightarrow a=-b\\\\\Rightarrow b=-a.$

That is, a is the additive inverse of b and b is the additive inverse of a.

Thus, the required TRUE statement is

if two integers combine to equal zero, then they are additive inverses of one another.
