So far, you've only studied systems of equations of lines. In Algebra, there are many more types of functions that you will learn about, in addition to lines. In the applet below, a few of these types of equations are given, in addition to a few lines.
You can see what these equations look like by clicking on the circle to the left of the equation. Using these equations, try to answer the following questions.
You can see what these equations look like by clicking on the circle to the left of the equation. Using these equations, try to answer the following questions.
1) Write a system of equations that has \(2\) solutions.
2) Write a system of equations that has \(3\) equations. 3) Write a system of equations that has no solutions. 4) Challenge: Can you come up with a system of equations that has \(4\) solutions? If so, what's the system and what are the solutions. |
