Answer:
C - $20.30
Step-by-step explanation:
-9.55 + (-10.75) = - 20.3
To solve for R you use PEMDAS
It would be a lot better if you zoomed in for these since it’s nearly impossible to read.
The standard equation of a circle with centre (xc,yc) and radius R is given by

Substituting
centre (xc,yc) = (4,-3)
R=2.5
The equation is therefore



or
(x-4)^2+(y+3)^2=6.25
Answer:
i cannot answer the value of X unless there is an equal sign but the equation simplified is 66-38x
