Which undefined geometric term is described as a location on a coordinate plane that is designed by an ordered pair (x, y) ?

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400

Enter the missing numbers in the boxes to complete the table of equivalent ratios. time (min) distance (km)? 36 9? 1512 ?
