Answer:
x = 1/2
Step-by-step explanation:
9x=4.5
Divide each side by 9
9x/9 = 4.5/9
x = 45/90
x = 1/2
Answer:
Center: (1, 5)
Radius: r = 5
Step-by-step explanation:
Step 1: Rewrite equation
x² - 2x + y² - 10y = -1
Step 2: Complete the Square (x2)
x² - 2x + 1 + y² -10y + 25 = -1 + 1 + 25
(x - 1)² + (y - 5)² = 25
Step 3: Find answers
Center = (h, k)
(1, 5) as Center
Radius = <em>r</em>
r² = 25
r = 5
