Practice solving these linear quadratic systems.

1. Solve algebraically:

             y = x2 + 4x + 3
             y = 2x + 6


 

2. Solve algebraically:

             y = -x2 + 2x + 4
             x + y = 4


 

3. How many points are there which satisfy the system:
             y = x2 - 6x + 8
             2y + x = 4


 

4. Solve graphically:

             y = x2 + 4x + 3
             y = 2x + 6

 

 

5. Solve algebraically:

             x2 + y2 = 25
             x - y = 5
 

 

 

6.

Determine which of the following is the solution for the system of equations y = x2 + 2x + 7 and y = x + 7.
 

Choose:

(-6,1) only
 (0,7) only
(-1,6) only
(0,7) and (-1,6)
 (0,7) and (-6,1)
(-1,6) and (-6,1)
