Best ResponseYou've already chosen the best response.0(x  a)^2 + (y  b)^2 = r^2 is the general form of a circle where (a,b) is the centre and r is radius compare this with your equation and you will get the center and radius of your circle

Best ResponseYou've already chosen the best response.1As I said  you can tell this JUST FROM the equation what is the x value of the centre of the original circle?

Best ResponseYou've already chosen the best response.1There is no point in posting th eanswers you need ot look at the equation and use the general equationgiven above to tell me what is th ex value of the original circle. This is th efirst step to th enaswer  so oyu need to do this first

Best ResponseYou've already chosen the best response.1to get to this question you MUST have studied the general equation for a circle as given by @welshfella so tell us wah is the centre point of the original circle

Best ResponseYou've already chosen the best response.0find the distance feom the center of the circle to the line represented by x=2, then that unidimensional distance should represent the center reflected on the line, and the radius will be the same, so that's pretty much it.
