Afamily went to a baseball game. they parked the car in a parking lot which charged $20. the cost per ticket was $28. write an equation for the total cost of going to the baseball game, where y is the total cost and x is the total number of people. if the family spent $188, how many people went to the game?

6 people went to the game.

28×6=188 if you include the cost of parking, which is 20.

a) y = 28x + 20

b) Plug in 188 for y and solve algebraically:

188 = 28x +20

subtract 20 from both sides

168 = 28x

divide 28 from both sides

6 = x

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
