Answer:
b=i*
or -i*
Step-by-step explanation:
11b^2-9=-68
11b^2=-59
b^2=-59/11
b=i* or -i*
"i" in this case is an imaginary number, equal to 
if you haven't learned about these yet, something is wrong with the question
The equation for a circle is (x-h)^2 +(y-k)^2=r^2
You just have to plug in your coordinates h is the x and k is the y.
The r is radius squared.
so, (x-2)^2+(y-(-5)^2=144
You have to be careful of those tricky negative values. When you distribute the y-(-5) it turns into y+5.
So your answer is D.
Im sorry wish i could help but the equation is a little confusing give me a few moments and i will figure out the answer okay?
