The answer is 45 because 45-15=30, therefore x=45.
Since 7 is greater than 5, you input it into the last equation.
2•(7) -7
14-7
7
The answer is 7!
Answer:
b
Step-by-step explanation:
because that is the correct answer believe me
Answer:
(x - 7)² + (y + 2)² = (2√13)²
Step-by-step explanation:
We already know that the center is at (7, -2), but must find the radius. The radius is the distance between the points (7, -2) and (1, -6):
r = √ [6² + 4²] ) = √(36 + 16) = √52 = √4√13 = 2√13.
Then the desired equation is (x - 7)² + (y + 2)² = (2√13)²
