What does the equation x2 + y2 = 16 represent as a region in the set of real numbers3?

Let us say that x and y are points that are located in the Cartesian coordinate. The sum of the squares of x and y gives the square of the radius of the circle. Therefore the equation x^2 + y^2 = 16 given that x and y are real numbers represent a Circle.

A circle has a general formula of x^2 + y^2 = r^2

answer: x=60

$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
