Integrated Algebra C & D

.
HW #1
1)  Is (-1, 5) a solution of each system? prove it.
x + y = 4
x = -1

2) Is (-1, 5) a solution of each system? prove it.
y = 5
x = y - 6

3)  solve by graphing.  check your solution.
y = x + 2
y = -2x + 2

4) solve by graphing. check your solution.
y = x + 4
y = 4x + 1

5) solve by graphing. check your solution.
3x + 4y = 12
2x + 4y = 8

HW #2
1) Explain how you can tell from a graph the number of solutions a system of equations contain.

2) Important!!! - print out HW#3 and bring to class tomorrow.  HW #3

HW #3
Finish the handout 7-1  HW #3

HW #4
solve and check using the substitution method

y = 4x - 8
y = 2x + 10

y = x - 2
2x + 2y = 4

3x - 6y = 30
y = -6x + 34

HW #5
solve and check using the substitution method

3x + 6y = -6
5x + y = -10

y = 2x
7x - y = 15

HW #6
solve by elimination

2x + 5y = 17
6x - 5y = -9

2x - 3y  = 61
2x + y = -7

20x + 3y = 20
-20x + 5y = 60

HW #7
solve by elimination

3x -10y = -25
4x + 40y = 20

7x + 15y = 32
x - 3y = 20

2x + 4y = 8
5x + y = -7
