Provide the reason for step 4 in the following proof.

a) additive inverse property

b) commutative property of addition

c)definition of subtraction

d)identity property of addition

prove :

The Correct option is

A) Additive Inverse Property .

Step-by-step explanation:

Identity Property of Addition :

In math, an identity is a number, n, that when added to other numbers, gives the same number, n.

The additive identity is always zero.

This brings us to the identity property of addition, which simply states that when you add zero to any number, it equals the number itself.

Statement                                      Reasons

1. -(a+b)+a = -a+(-b)+a                   1.Distributive Property

                = -a+a+(-b)                    2.Commutative Property of Addition

                = 0+(-b)                         3. Additive Inverse Property

                = -b                               4. Identity Property of Addition

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
