Answer:
radius = 11
Step-by-step explanation:
The equation of a circle in general form is
x² + y² + 2gx + 2fy + c = 0
with radius = 
x² + y² - 20x + 14y + 28 = 0 ← is in general form
with 2g = - 20 ⇒ g = - 10
2f = 14 ⇒ f = 7 and c = 28, thus
radius = 
= 
= 
= 11
Answer:
C) 0.066...
Step-by-step explanation:
1/15 = 0.066...
You could eliminate B and C as 15 (numerator from question) is not a multiple of 10. You can eliminate A as the numerator of 15 from the question is larger than 10 and will result in a number less than 0.1.

Answer:
K= -3
Step-by-step explanation:
-3k+6=15
-6 -6
-3k=9
/-3 /-3
k=-3
subtract 6 from both sides.
divide each side by -3 to get K alone
-3 is your answer.
