Andrew sold $50 less than sarah did and evan sold $25 more than Sarah. these quantities can be communicated symbolically. if x= the amount that sarah sold, which of these represents the amount sold by the other two people? A. andrew=50-x, Evan= x+25
B. Andrew=x-50, Evan=x+25
C. andrew=x-50, evan=25x
D. andrew=50-x, evan=25x

25 ! the line of best fit is h = 5a + 86. predict the height at age 16. show your work.

How do you solve a question like this?

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
