Find the center and the radius of the circle with the equation: x^2-2x+y^2+4y+1=0?

Alogical argument that is presented in graphical form using boxes and arrows is called?

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.
