Triangle ABC is dilated using the dilation rule Do.5(x, y) to form triangle A'B'C'. Point A is located at (10,7.5), point B is located at (-5, 2), and point C is located at (0.5, -7).
What are the coordinates of A'?
What are the coordinates of B'?
What are the coordinates of C'?

Write the expression in simplified radical form. show all steps and work including any foil method work. (hint: use the conjugate. no decimal answers.) (9-2√3)/(12+√3)

Which statement explains how you could use coordinate geometry to prove the opposite sides of a quadrilateral are congruent? a. use the slope formula to prove the slopes of the opposite sides are the same. b. use the slope formula to prove the slopes of the opposite sides are opposite reciprocals. c. use the distance formula to prove the lengths of the opposite sides are the same. d. use the distance formula to prove the midpoints of the opposite sides are the same.

How can you check that you have correctly converted frequencies to relative frequencies?
