1) Solve the system of equations graphically and check:
24x + 8y = 56
12x – 24y = 168
2) Solve the system graphically and check
(4 CHECKS!!!) – This works. I promise!
y = 2x2 – 4x – 7
y – 7 = 2(x – 3)

3) A jar of change has $39.60 in it. There are 6 fewer quarters than double the dimes. There
are 6 more nickels than 5 times the amount of dimes. How many nickels, dimes, and quarters are
in the jar? (There are no pennies.)
4) Solve the system algebraically and check:
11x – 4y = -86
9x + 6y = -24
5) Factor each (Please FOIL check…. you never know. One might be prime….)
a) 25x2 – 1
b) x2 – 19x + 84
c) x2 – x + 56
d) 8x2 + 10x + 3
