Given the number below, which value of x would make the mean and the median of the data set the same? Data set: 9, 7, 5, 6, 7, X A 4

B 7

C 8

D 9

Simplify (a/b - b/a) times (a - a^2/a+b) a - a^2/a=b is a mixed number

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

If 3x+8=3x+8 is it one solution or no solution
