Answer:

Step-by-step explanation:

(3x - 3) + 3 = (3x + -3) + 3

<em>use the Associative Property of Addition: (a + b) + c = a + (b + c)</em>

= 3x + (-3 + 3)

<em>use Inverse Property of Addition: a + (-a) = (-a) + a = 0</em>

= 3x + 0

<em>use Identity Property of Addition: a + 0 = 0 + a = a</em>

= 3x

For a new customer, a video store charges $10 for a rental card plus $2 per movie. Using the linear equation (y=mx+b) you wrote,

netineya [11]

Given:

Charges for rental card = $10

Charges for movie = $2 per movie

To find:

The linear equation for given situation and find the cost to rent 6 movies.

Solution:

Let y be the total cost for x number of movies.

Cost of one movie = $2

Cost of x movies = $2x

Total cost = Charges for rental card + Charges for x movies

$y=10+2x$

Put x=6 to find the cost of 6 movies.

$y=10+2(6)$

$y=10+12$

$y=22$

Therefore, the total cost for a new customer to rent 6 movies is $22.
