Use completing the
square to identify the
center and radius of the
following circle
x2 + y2 + 2x - 10y - 23

center: (-1 , 5)

radius: 7

Step-by-step explanation:

circle: (x – h)²+ (y – k)² = r², with the center at (h, k) and the radius "r"

x² + y² + 2x - 10y - 23 = (x + 1)² + (y - 5)² - 49 = 0

(x + 1)² + (y - 5)² = 49 = 7²

center: (h , k)   (-1 , 5)

radius: 7

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
