If f(x) = x2 + 7, what is the value of f(3)? A) 2 Eliminate B) 12 C) 13 D) 16 E) 17

D

Step-by-step explanation:

To evaluate f(3) substitute x = 3 into f(x), that is

f(3) = 3² + 7 = 9 + 7 = 16 → D

$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
