Rearrange to standard form:-
x^2 - 10x + y^2 = 11
(x - 5)^2 - 25 + y^2 = 11
(x - 5)^2 + y^2 = 36
Center of circle = (5, 0) and radius = sqrt36 = 6
Multiply both sides by 3 and get 2x - 20 = 6x
Then subtract 2x from both sides and get
-20 = 4x. Divide both sides by 4 and then get x = -5
Y = mx + b
m: slope
b: y -intercept
so the y intercept is -4 or (0,-4) as a coordinate
?/8 = 3/?
Multiplying both sides by 8, then “?” gives
8? * ?/8 = 8? * 3/?
?*? = 24
The number, then, is sqrt(24), or 2 sqrt(6), which is approximately 4.90.
