True or false

for a real number a, a + 0 = a.

for a real number a, a + (-a) = 1.

for a real numbers a and b, | a - b | = | b - a |.

for real numbers a, b, and c, a + (b ∙ c) = (a + b)(a + c).

for rational numbers a and b when b ≠ 0, is always a rational number.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

i believe that the slope of the line is -5

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
