Which set of ordered pairs could represent a function? (12, –3), (12, 0), (12, 8), (12, 7)
(8, 3), (4, 9), (1, 1), (4, 2)
(5, 6), (6, 6), (7, 6), (8, 6)
(5, 5), (7, 7), (9, 9), (11, 12)

C and D both look correct???

I think d is a one on one function while c is a function but a multiple relation function, sorry if im wrong

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
