The circle equation is in the format (x – h)2 + (y – k)2= r2, with the center being at the point (h, k) and the radius being "r".
Therefore (x – 1)2 + (y +5)2= 102
x2 + y2 + 1 - 2x + 25 + 10y = 100
x2 + y2 - 2x + 10y = 74
Answer:
$48.72
Step-by-step explanation:
5.6 liters x $8.70 per liter= $48.72 total cost
I think it’s X=-3+(the square root of 2)
Is C and D because 10x^2-6x^2=36+64
4x^2=100
x^2=25
x= -5 or 5
