## Closed Captioned Video: Algebra Applications: Systems of Equations # Description

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.
A Video Transcript is available for this tutorial.

## Closed Captioned Video: Algebra Applications: Systems of Equations, Segment 1: Profit and Loss # Description

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.
A Video Transcript is available for this tutorial.

## Closed Captioned Video: Algebra Applications: Systems of Equations, Segment 2: Encryption # Description

Secret codes and encryption are ideal examples of a system of equations. In this activity, students encrypt and decrypt a message.
A Video Transcript is available for this tutorial.

## Closed Captioned Video: Algebra Applications: Systems of Equations, Segment 3: Ballistic Missiles # Description

A ballistic missile shield allows you to shoot incoming missiles out of the sky. Mathematically, this is an example of a linear-quadratic system. Students graph such a system and find the points of intersection between a line and a parabola.
