Which equation represents a circle that contains the point (-5. -3) and has a center at (-2, 1)?
Distance formula: (x2-x1)^2 + (y2-y1)^2
A. (x - 1)2 + (x + 2)2 = 25
B. (x + 2)2 + (-1)2 = 5
C. (x + 2)2 + (x - 1)2 = 25
D. (x - 1)2 + (y + 2)2 = 5

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
