Identify the translation rule on a coordinate plane that verifies that triangle a(-5,1), b(-2,7), c(0,1) and triangle a'(-3,2), b'(0,8), c'(2,2) are congruent. a) (x, y) → (x - 1, y + 2) b) (x, y) → (x + 2 , y + 1) c) (x, y) → (x - 2, y + 1) d) the triangles are not congruent

Solve the problem by making up an equation. a man could arrive on time for an appointment if he drove the car at 40 mph; however, since he left the house 15 minutes late, he drove the car at 50 mph and arrive 3 minutes early for the appointment. how far from his house was his appointment?
