This is a weird one. I'm going to work it, but I also want you to look back at the
book or the worksheet and make sure that you copied it correctly.
Because it's weird, I tell you.
| y + 9 | > 4
Subtract 9 from each side of the inequality:
<em> | y | > -5</em>
OK. Now, here we go:
'Absolute value' means just the size of the number, no matter whether it's
negative or positive. <em>So the absolute value of every number is positive</em>.
Got that ? <em>The absolute value of every number is positive</em>.
So <u>EVERY</u> number is a solution to this inequality. It doesn't matter what number
' y ' is, its absolute value is always positive. And if the absolute value is always
positive, then it's definitely always greater than -5 .
Weird ? I told you so.
