Integers are like -1,0,1,2,3,4....
-3 and 2/5 is -3.4
-2.7
between -3.4 and -2.7 is -3
integers is -3
Answer:
0 (zero)
Step-by-step explanation:
It is the only Rational number, which is its own additive inverse.
Additive inverse of ….
2 is -2
-3 is 3
7/9 is -7/9
-1 is 1
1 is -1
I gave a few examples above, each is additive inverse of the other because their sum = 0. For finding additive inverse we only need to change its sign., and if we need both numbers equal, it has to be 0. Since 0+0 = 0.

X² - 3x - 4 = 0
Reverse FOIL method . . .
(x - 4)(x + 1) = 0
one of the paranthesis has to be equal to zero if the other is not . . .
x - 4 = 0
<u><em>x = 4</em></u>
x + 1 = 0
<u><em>x = -1</em></u>
