Aww. Advanced Functions. NotTim's Weakness.
3x+11 > 26 3x > 26-11 3x > 15 x > 15/3 x > 5 So the solution is x > 5 To graph this, draw out a number line and draw an open circle at 5. Then shade to the right of that open circle.
Aw. I was gunna say like try it as if > was a =, but I know that's wrong now...
Thank you so much!!! That really helped i just always forget the formula!
wait...jim...you got the time to teach me how you did this?
The idea is to solve this as if you would any equation. So if you can solve 3x+11 = 26, then you can solve 3x+11 > 26 Just think of the ">" as a "=". The sign will only change if you happen to multiply or divide both sides by a negative number.
Does that make sense?
how would i graph it if the sign was the greater to or equal to sign? kidn of like > -
Instead of an open circle, use a closed circle.
except the line would be directly underneath the greater to sin
so it would be like...|dw:1332643784120:dw|
Yes and now shade to the right of the closed circle (since the sign was a greater than or equal to sign)
ok so: 3x+18>36 (with the line under the greater than sign) would equal x>6(again, with the line under the greater than sign)! and the graph would look like |dw:1332644043109:dw| but what would number would the circle represent? Like the last one represented 5?
Yes the solution to \[\Large 3x+18 \ge 36\] is \[\Large x \ge 6\] which means you plot a closed circle at 6 and shade to the right.
YES!!! i got it right!! Thank you so much you are a great teacher!
You're welcome. Glad I could be of help to you.
And congrats on getting it right
