Estephania needs 19 bottles of pepto bismal. The rule at Bismal Co. is that you can only buy five bottles per day. She must also give six bottles to her third cousin’s daughter’s husband Carlisle. If n represents the number of days it will take to get her nineteen bottles and Carlisle’s six, write an equation representing Estaphania’s problem.
Y = a(x + 2)(x - 3) : equation of the parabola in factored form 10 = a(5 + 2)(5 - 2) : (5 , 10) is a point on the graph of the parabola and therefore satisfies the equation of the parabola. a = 5/7: solve the above equation for a.
