The answer is 14. if n equals 3 and you use the equation instead of n. 3+11 that would equal 14
C is the answer

Answer:
Step-by-step explanation:
x+y=17 is NOT the equation for any circle. You have omitted the exponents. The equation for the circle should be
x^2 + y^2 = 17.
:::::
Plug the coordinates of D into the equation.
(-4)² + (-1)² = 17, so D is on the circle.
Plug the coordinates of E into the equation.
1² + 4² = 17, so E is on the circle.
:::::
Slope of DE = (-1 - 4)/(-4 - 1) = 1
Slope of perpendicular to DE is -1.
Midpoint of DE: ((-4+1)/2, (-1+4)/2) = (-1.5, 1.5)
Point-slope equation for perpendicular bisector:
y-1.5 = -(x+1.5)
y = -x
:::::
Center of circle is (0,0)
0 = -0, so y=-x passes through the center.
Answer: pretty sure lily is right
Step-by-step explanation:
Answer:
$112,710
Step-by-step explanation:
so first we have to find what is 15% of 86700
so 15/100×86700=$13005
so it is written that 86700 is in 2012 means 2010 it will be
2 times more which means 30% that means just have to do is multiply it two times which makes it $26010
so $86700+$26010=$112710
