2) x2 + 2x – 80
3) x2 + 15x + 54
4) x2 – 21x + 90
5) x2 – 121
6) 9x2 – 196
7) 8x2 – 24x – 320
8) x9 + 13x8 + 36x7
9) 9x7 + 9x6 – 504x5
10) 7x8 – 175
11) 36x2 – 16
12) 144x4 – 64

19) 225x2 – 36
20) 81x36 – 144
21) 196x15 – 49x7
Part II:
1) -2|8x – 4| - 5 = -93
2) ⅔|2x + 3| - 12 = -6
3) 11x + 6 – 3x - 17 = 81
4) 7x – 12 = 11x + 20
5) 7(4x + 1) + 4(6 - 3x) = 7
6) 4(5x – 1) = 7(5x + 8)
7) 5(6x – 4) – 8(7x + 5) = -99
8) 10(9x + 3) = 8(12x - 6)
9) 93 – 7x = 191
10) 48 - ⅜x = 72
Part III:
1)
A jar of change has $37.40 in it. There are 6 more quarters than double the nickels.
There is 1 less dime than double the amount of nickels. How many nickels, dimes,
and quarters are in the jar? (There are no pennies.)

are $.09/min. If there were 4 more introductory minutes than double the additional
minutes, how many minutes were billed at each rate? How long was the phone call?
Part IV: Solve algebraically:
1) 14x – 42y = 210
-8x + 24y = 120
2) 22x + 11y = 33
16x + 8y = 24
3) 6x = 5y - 2
7y = 2x + 22
