Answer:
a reflection over the x-axis
Step-by-step explanation:
say you plotted (1,1) and the plotted (-1,1). The result would be a reflection over the x-axis.
First you would start getting the denominators to the same number and you could do this by multiplying 9/10 by 4, and 7/8 by 5 to get the denominators to 40 and when you add the fractions you get 71/40 so the answer would be D. About 2

3 students = 4.25 x 3 = 12.75
Total = $23.75
