Answer:
Center: (3,5)
Radius: 2
Step-by-step explanation:
x² + y² - 6x - 10y + 30 = 0
Put equation into center-radius form. First regroup terms:
(x²-6x) + (y²-10y) = -30
Complete the squares:
(x²-6x+3²) + (y²-10y+5²) = -30 + 3² + 5²
(x-3)² + (y-5)² = 4 = 2²
Center: (3,5)
Radius: 2
Answer:
1. 81
2. 108 1/2
3. 189 1/2
Step-by-step explanation:
Y=1.50x+7.50. 7.50 is the y intercept and 1.50 is the rate of change or slope
100,000 is basically the same thing as 100k
