The number k and 1.4 are additive inverses.
1 answer:
For this case we have the following definition:
The additive inverse of a number is the opposite of that number, that is, the additive inverse of a number x is - x. The sum of a number and its additive inverse is equal to zero.
We have then:
From here, we clear the value of k.
Then, we place the values on the number line.
