4. What number is its own additive inverse? Why?

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.

Hope this Helps!!!

step-by-step explanation:

2+4x6-8/10= 25.2

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
