Asap someone me! , i beg my grade is going down and i can only count on u guys!

Additive inverses combine to get 0. So, k is -1.4. The sum is 0. Hopefully that will help.

An additive inverse is a number and it's positive or negative equal away from zero. Both numbers added together must equal zero. So 8 and -8 are additive inverses because they equal zero. 10.5 and -10.5 are additive inverses.

For your problem above, 1.4 is the additive inverse of -1.4 because added together they equal zero.

Given #= 1.4
k= -1.4
sum= 0

Hope this helps! :) Good luck!!
