2/3y+4 as an algebraic expression

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.

Find the constant of variation for the relation and use it to write an equation for the statement. then solve the equation.

How is working backward similar to solving an equation?
