Help I'm Algebra 1 Brain Dead
Which graph represents the solutions to the inequality \[|2x-4| \ge4\]
I need some help @phi
@pooja195 I need some help real quick its algebra 1 can you help?
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) ________________________________
@pooja195 is It option one because that one makes sense
am I right phi?
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)
So D because the others are open circles
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
OK thanks so much
