The cost of coffee is determined by the type of coffee beans that are mixed together. the cost of a local mix of arabica and robusta beans is modeled by the equation below, where a = the pounds of arabica and r = pounds of robusta: (2 points) 700a + 1200r = 1,000,000 if a mixture contains 1000 pounds of arabica beans, how many pounds of robusta beans should be in the mixture? r = pounds

Demonstrate the proof of your new polynomial identity through an algebraic proof and a numerical proof in an engaging way! make it so the whole world wants to purchase your polynomial identity and can't imagine living without it! you must: label and display your new polynomial identity prove that it is true through an algebraic proof, identifying each step demonstrate that your polynomial identity works on numerical relationships create your own using the columns below. see what happens when different binomials or trinomials are combined. square one factor from column a and add it to one factor from column b to develop your own identity. column a column b (x − y) (x2 + 2xy + y2) (x + y) (x2 − 2xy + y2) (y + x) (ax + b) (y − x) (cy + d)
