Hello,
x^2+y^2+8x-6y+21=0
Rewritten in the form of a standard circle equation:
(x-(-4))^2+(y-3)^2=2^2
Therefore, the circle properties are:
(a,b)=(-4,3),r=2
The radius of the circle whose equation is <span>x^2 + y^2 + 8x - 6y + 21 =0 is 2.

Answer:
44
Step-by-step explanation:
6(8)-4 = 48-4= 44
The property illustrated is the Associative property of multiplication
Answer:
-2/35
Step-by-step explanation:
Slope y-intercept form : y = mx + b
Here m is the slope and b is the y-intercept
Write the given equation in slope y-intercept form.
Well, if 4 muffins cost $5.24, then we can do 5.24 ÷ 4 = 1.31 to know that one muffin costs 1.31. Now we can do 1.31 x 5 = 6.55 to know 5 muffins cost 6.55.
