I wanna say the 1st or the last one
Answer:
(x + 7)^2 + (y + 3)^2 = 4
Step-by-step explanation:
The standard equation of a circle is:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius. We can substitute the information given to obtain:
(x + 7)^2 + (y + 3)^2 = 4
Answer:

6. 106.25
7. No, the associative property does not work for subtraction or division, they do not hold for the associative property. For example,
2+ (3+4) = (2+3) + 4 2- (3-4) = (2-3) – 4
2+7 = 5+4 2 + 1 = -1-4
9 = 9 3 = -5, which is not true
8. No, the commutative property does not work for subtraction or division, they will give a different result. For example,
5+6 = 6+5 5-6 ≠ 6-5

Answer:
(x,y) (9,4)
Step-by-step explanation:
-2x+7y = 10
x -3y = -3 (move x to the other side)
-2x +7y = 10
x = -3 + 3y (put in for x)
-2 (-3 +3y) +7y =10 ( slove for y)
6-6y +7y = 10
6+y = 10
y = 10-6
y = 4
go back slove for x
x = -3+3x4
x = 9
