Help Me<3 Part 1: Solve |2x+7| -3 > 10. You must show all work. Part 2: Use complete sentences to describe the graph in words.
add 3 on both sides, try to get the absolute value by itself \[|2x+7|>13\]
Now what 2 equations can you write from what @marird15 wrote. Think about what absolut value means
2x+7>13 or -2x-7>-13? im not sure about the seond one
you have it right except nothing happens to the 2x+7
Do you see why?
so only the 13 becomes a negative?
ya because the expression is saying that (2x+7) = a positive or negative 13. because when the abs value is applied it becomes positive. If you apply the negative sign to the 2x+7 you are changing the equation
I'd suggest working out the math for both just so you can see it
if you do the math for your 2 equations you wrote above you'll see that they are the same equation. 2x+7=13 <-> -2x-7=-13 <-> -1(2x+7)=-1(13)
Now you'll have to refresh me on something. I vaguely remember that you need to flip the < when you do what?
