Help me with this problem because I do not understand it!
1 answer:
Answer:
- The center is (-1, 5) and radius is 9
Step-by-step explanation:
<u>Given function</u>
- x² + 2x + y² = 55 + 10y
<u>Put the equation into standard form:</u>
- (x - h)² + (y - k)² = r², where (h, k) is the center, r- radius
<u>Compete square for both x and y:</u>
- x² + 2x + y² = 55 + 10y
- x² + 2x + 1 + y² - 10y + 25 = 81
- (x + 1)² + (y - 5)² = 9²
The center is (-1, 5) and radius is 9
