8(2z-6)
Distributive property

16z-48

Step-by-step explanation:

8(2z-6)

8*2z-8*6

16z-48

16z - 48

Step-by-step explanation:

8(2z-6)

To do the Distributive Property, multiply the number outside of the parenthesis by each number inside the parenthesis, to get something like this:

8(2z) and 8(-6)

16z - 48

((If you get a positive number for the second number then it'd be 16z + 48 but since it's negative it's 16z - 48))

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
