Which property of real numbers is shown below -6+6=0

a.) associative property
b.) commutative property
c.) identity property
d.) inverse property

The property is inverse property        

Step-by-step explanation:

Given the expression

-6+6=0

we have to find which property of real numbers is shown

Associative property says that

when three or more numbers are added, the sum is the same when grouping order change i.e

a+(b+c)=(a+b)+c

Commutative property says that "a + b = b + a"

Identity property says the sum of any number and zero is the original number.

Inverse Property of Addition says that any number added to its opposite will equal zero i.e

a+(-a)=0

Here, 6 is added to its inverse that is -6 which gives the result 0

Hence, the property is inverse property

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
