Which of the following is an example of the additive identity?
a +(-a) = 0
a+0=0
a+0= a

a+0= a

Step-by-step explanation:

we know that

The additive identity property says that if you add a real number to zero or add zero to a real number, then you get the same real number back

so

Let

a > a real number

a+0=0+a=a

therefore

a+0= a

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5

fourth month

step-by-step explanation:

it is the one with the most keychains.
