The circle is in A, so (-1, 4) coords
(x - xo)² + (y - yo)² = r²
(x - (-1))² + (y - 4)² = r²
(x + 1)² + (y - 4)² = r²
And the radius is the length of segment AC
distance of AC is






So r = 5
(x + 1)² + (y - 4)² = 5²
(x + 1)² + (y - 4)² = 25
We can have:
(10x - 2) - (5x + 2)
Or:
(7x + 3) - (2x + 7)
-6x + 10 is the answer!!!!
5 hours and 20 minutes because 1/3 as a decimal is 0.3 continued (i wrote down 0.33 so its simplified) and 0.33 decimal hours is 20 minutes.
