7 System of Equations Use 2 methods to solve y = x + 2 y = ( x – 4) 2 You and your partner must each choose a different method. Compare your answers. Make any edits you want.

©Evergreen Public Schools System of Equations Aries bought a new Toyota Highlander in By researching values she finds the equation V ( t ) = 32000(0.87 t ) can be used to estimate the value of the car each year, where t is the number of years she owned the car. She has a loan amount of with $600 monthly car payments on a 5 year loan. Write an equation to find the unpaid balance of the loan for t years. When will the value of the car be less than the value of the loan? What is the car worth?

©Evergreen Public Schools Debrief Consider solving a system with two linear equations similar to solving a system with one linear and one quadratic equation compared to solving a system with one linear and one exponential equation How are they similar? How are they different?

©Evergreen Public Schools Learning Target Did you hit the target? I can solve problems with systems of equations and inequalities. Equations can be linear, exponential or quadratic. Rate your understanding of the target from 1 to 5. 5 is a bullseye!
