Determine if the expressions below are equivalent by simplifying. justify your answer.

5(x + 2) + 4 + 10x

and

8x – 9 + 8x + 23

You are constructing a histogram for scores that range from 70 to 100 in whole points. frequencies range from 3 to 10; that is, every whole-point score between 60 and 100 occurs at least 3 times, and at least one score occurs 10 times. which of these would probably be the best range and size for the score intervals along the x-axis?

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1

Which of the following best describes the figure?
