Solve and graph the absolute value inequality: |2x + 4| > 14 Choices: http://prntscr.com/7043xj @JackofallTradez @matlee I know D isn't right because I put that before and got it wrong.
Well, we know 2x+4>14 or 2x+4<−14 2x+4>14 (Possibility 1) 2x+4−4>14−4 (Subtract 4 from both sides) 2x>10 2x > 10 -- --- 2 2 (Divide both sides by 2) x > 5
Possibility 2: 2x+4<−14(Possibility 2) 2x+4−4<−14−4(Subtract 4 from both sides) 2x<−18 2x < -18 --- ---- 2 2 (Divide both sides by 2) x < −9 Answer: x>5 or x<−9
That leaves me going between A and B... I think lol
Well which one is it?\[A~or~B\]
I'm leaning more towards B... I'm not sure, it's been 5 months since i've done this unit.
Well B is Incorrect, so that makes the answer A. The line graph is separated just like choice A
What about open and closed circles though? I thought the -9 circle on A was incorrect...
Closed circles are when they are Less-than or Equal to/ Greater-than or Equal to
Ah, okay. Thanks.
Yeah, No Problem :)
