Notes and Videos for College Algebra Final

Practice Problems for College Algebra Final

Notes for the Week 12 Videos
- #1 - Solve a System of 2 linear equations in 2 variables
- #2 - Solve an independent system of 3 linear equations in 3 variables by elimination.
- #3 - Solve a dependent system of 3 linear equations in 3 variables, with infinitely-many solutions
- #4 - Show that the dependent system of 3 linear equations in 3 variables given has no solutions.

Notes for the Week 14 Videos - These are similar to the Week 14 solutions, but they are board work from the videos, rather than straight-up solutions that I released, previously. Also, the system of linear inequalities is a brand-new system, for more practice.
- #1 - Partial Fractions
- #2 - Graph a system of linear inequalities
- #3 - Parabolas: Vertex, Focus and Directrix
- #4 - Ellipses: Center, Vertices and Foci. "The box."
  - #4a - Center at the origin
  - #4b - Center NOT at the origin
- #5 - Hyperbolas: Center, Vertices, Asymptotes, and Foci. Also "the box."
  - #5a - Hyperbola with vertex at the origin
  - #5b - Hyperbola with vertex NOT at the origin
- #6 - Binomial Theorem and Binomial Coefficients
  - #6a - Pascal's Triangle
  - #6b - Full-blown Binomial Theorem
- #7 - Permutations: Choose and Arrange.
- #8 - Combinations: Choose!
