In 1989 a locally-owned car company sold 2,881 cars. 
in 2002, the car sales rose to 4,232. 
what was the average rate of change for the total number of cars sold?
  a. 
1,351 cars per year
  b. 
9.62 cars per year
  c. 
3,557 cars per year
  d. 
104 cars per year

D. 103 12/13 or about 104

First sort the data into two sets of points, (1989,2881), (2002, 4232).

Now use the slope equation with your numbers.

(y2-y1)/(x2-x1)

(4232-2881)/(2002-1989)

1351/13=

103 12/13 or about 104

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
