If 3 times a certain number is increased by 4 the result is 28. What is the number? If x is "the number," which of the following equations could be used to solve for the number?
3( x + 4) = 28
3 x= 4 + 28
3x+ 4 = 28

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 f(x)= sqrt4x+9+2, which inequality can be used to find the domain of f(x)?
