Someone please help!! I would really appreciate it! This is my math test!

Recall the definition of a polynomial expression. find two polynomial expressions whose quotient, when simplified,is. use that division problem to determine whether polynomials are closed under division. then describe how theother three operations-addition, subtraction, and multiplication-are different from division of polynomials.

Consider the system: y = 3x + 5 y = ax + b what values for a and b make the system inconsistent? what values for a and b make the system consistent and dependent? explain

Ab and bc form a right angle at point b. if a= (-3,-1) and b= (4,4) what is the equation of bc?
