    2x−4≥4(Possibility 1) 2x−4+4≥4+4(Add 4 to both sides) 2x≥8 divide both sides by 2 (find the answer) _______________________ 2x−4≤−4(Possibility 2) 2x−4+4≤−4+4(Add 4 to both sides) 2x≤0 divide both sides by 2 (find the answer) ________________________________

    I guess you don't understand pooja's answer? 2x≥8 if you divide both sides by 2 you get x≥4 the line under the > means equal to , so you want a filled in dot at 4 x is next to the "big" side of > , which means x is bigger than (or equal to) 4 for example, 5 , 6, etc so part of the answer should show all the numbers bigger than 4 (an arrow pointing to those numbers)

    choice A has solid circles, but the blue line shows numbers between 0 and 4 and we want numbers bigger than 4 so yes choice D
