System of Equations

Representing systems of equations in more than two variables by using matrix equations. Using the equations to solve real-world problems.

Mapped to CCSS Section# HSA.REI.C.7, HSA.REI.C.8, HSA.REI.C.9

Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically. For example, find the points of intersection between the line y = -3x and the circle x^2 + y^2 = 3. Represent a system of linear equations as a single matrix equation in a vector variable. Find the inverse of a matrix if it exists and use it to solve systems of linear equations (using technology for matrices of dimension 3 × 3 or greater).
