1. Can a system of quadratic-quadratic equations can have exactly one solution?

2. Can a system of quadratic-quadratic equations has no solutions if the graphs do not intersect?

3. Is it impossible for a system of linear-quadratic equations to have an infinite number of solutions?

4. Can the solution to a system of equations can be verified by substituting the solution into one of the original equations?
