VIDEO: Algebra Applications: Systems of Equations 
In this episode of Algebra Applications, students explore various scenarios that can be explained through the use of systems of equations. Such disparate phenomena as profit and loss, secret codes, and ballistic missile shields can be explored through systems of equations. This video includes a Video Transcript: https://www.media4math.com/library/videotranscriptalgebraapplicationssystemsequations 

VIDEO: Algebra Applications: Systems of Equations, Segment 1: Profit and Loss 
Profit and loss are the key measures in a business. A system of equations that includes an equation for income and one for expenses can be used to determine profit and loss. Students solve a system graphically. This video includes a Video Transcript: https://www.media4math.com/library/videotranscriptalgebraapplicationssystemsequationssegment1profitandloss A Promethean Flipchart is available for this video: https://www.media4math.com/library/prometheanflipchartalgebraapplicationsprofitandloss 

VIDEO: Algebra Applications: Systems of Equations, Segment 2: Encryption 
Secret codes and encryption are ideal examples of a system of equations. In this activity, students encrypt and decrypt a message.

VIDEO: Algebra Applications: Systems of Equations, Segment 3: Ballistic Missiles 
A ballistic missile shield allows you to shoot incoming missiles out of the sky. Mathematically, this is an example of a linearquadratic system. Students graph such a system and find the points of intersection between a line and a parabola.

VIDEO: Algebra Nspirations: Solving Systems of Equations 
Written and hosted by internationally acclaimed math educator Dr. Monica Neagoy, this video introduces students to systems of linear equations in two or three unknowns. To solve these systems, the host illustrates a variety of methods: four involve the TINspire (spreadsheet, graphs and geometry, matrices and nSolve) and two are the classic algebraic methods known as substitution and elimination, also called the linear combinations method. The video ends with a summary of the three possible types of solutions. Concepts explored: equations, linear equations, linear systems.
