Lara solved an equation incorrectly, as shown below: step 1: 2x = 18 step 2: x = 18 − 2 step 3: x = 16 which statement best explains why step 2 is incorrect in lara's solution? a) she did not divide 18 by 2. b)she did not add 2 to 18. c)she did not multiply 18 by 2. d) she did not multiply 18 two times.

Monica build a remote control toy airplane for science project to test the plane she launched it from the top of a building the plane travel a horizontal distance of 50 feet before landing on the ground a quadratic function which models the height of the plane in feet relative to the ground at a horizontal distance of x feet from the building is shown

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) .

Find the value of x for which the lines are parallel.
