The thing that i leant this week are: solving systems of equation graphically, solving systems of equations algebraically
systems is when 2 or more equations are needed to final a solution.
The equation of a linear function and the equation of a quadratic function from a linear-quadratic system of equations
The coordinates of a point of intersection of the graphs of the equations in a system are a solution of the system.
The equations of two quadratic functions form a quadratic-quadratic system of equations.
a solution of a linear-quadratic system of equations is an ordered pair,(x,y),that satisfies both equations in the system. The system may have 0,1,or2 solutions.
A solution of a quadratic-quadratic system of equations is an ordered pair that satisfies both equations in the system. The system may have0,1,2,or infinite solution.
