What is the equation of a circle with center (-3,-5) and radius 4?
O A. (x+3)2 + (y + 5)2 = 4
O B. (x-3)2 + (y- 5)2 = 16
O C. (x-3)2 + (y- 5)2 = 4
O D. (x+3)2 + (y + 5)2 = 16

D. (x + 3)² + (y + 5)² = 16

General Formulas and Concepts:

Algebra I

Coordinates (x, y)

Pre-Calculus

Center-Radius Form: (x - h)² + (y - k)² = r²

(h, k) is the centerr is radius

Step-by-step explanation:

Step 1: Define

Identify variables

Center (h, k) = (-3, -5)

Radius r = 4

Step 2: Find Equation

Substitute in variables [Center-Radius Form]:                                                (x - -3)² + (y - -5)² = 4²Simplify:                                                                                                             (x + 3)² + (y + 5)² = 16

The best way to plot them is by month.170-110 =$60.as, we are supposed to plot in months and the above calculation is in year, convert it into months60/5 = $5 each monthso, the coordinates would be 0,110 1,115 2,120 3,125and you x will be the monthand your money will be the y axis
