Write the standard equation of the circle with center (-9, 5) and a diameter of 22.

"(x - x0)^2 + (y - y0)^2 = r^2 

So the radius is 11, half of diameter 

x0 = -9 
y0 = 5 

so (x+9)^2 + (y-5)^2 = 11^2 
(x+9)^2 + (y-5)^2 = 121 

Hope that helped!"

False because how does that work?

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
