Simplify the polynomial, then evaluate for x = 1 and y = – 2. 2x+y + 3x y2 – 3xy + 4x2 y + y2 – 5x y2

6x²y – 2xy2 – 3xy + y2; – 2

6x2 y – xy2 – 3xy; – 10

6x2y - 2xy2 – 3xy + y2; – 10

6x²y – xy2 – 3xy; – 14

Need help simplifying the polynomial

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.
