Answer» A) -(-a)addititve inverse is the number when added to a given number will YIELD zero. The additive inverse of 2 is −2.suppose y and z are additive inverses of x. Then y = y + 0 = y + (x + z) = (y+x)+z = 0 + z = z. Remark: Of course the additive inverse of x equals (-1)x. To PROVE this, since we KNOW that the additive inverse is unique, it is enough to show that (-1)x is an additive inverse of x, i.e. that x+(-1)x=0.here,a-(-a) = a+a ≠ 0hope it helps yougive me a heartMark me as BRAINLIEST pls...pls...pls... |
