Line cd is perpendicular to line ab and passes through point c(5, 12). if the coordinates of a and b are (-10, -3) and (7, 14), respectively, the x-intercept of cd is__ . the point lies on cd. 1. a) (12,0) b) (15,0) c) (17,0) d) (19,0) 2. a) (-5,24) b) (-2,19) c) (7,-10) d) (8,11)

Circle a has center of (2,3) and a radius of 5 and circle b has a center of (1,4) and a radius of 10. what steps will show that circle a is similar to circle b 1) dilate circle a by a scale factor of 2 2) translate circle a using the rule (x+1,y-1) 3) rotate circle a 180 degrees about the center 4) reflect circle a over the y-axis
