Hello guys how's school going

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) .

For what values of the variable x is the expression square root of 7x+14+ square root of 7-x a real number?

In an improper fraction, is the numerator equal to, less than, or greater than the denominator
