Since I know that all of you out there are still using the Algebra that you learned in Algebra I, I would like to post 4 questions on this blog.
Post your answers in the comments. (If anyone can get all 4 of them right, maybe I will put an extra point on every Algebra exam... or something like that. Am I allowed to do that? Of course I am! I am the teacher! Ha, ha ha! Hmm... maybe if nobody can get all 4 of them right, I will take off points... Oh yeah! ...Wait a minute, hold those phones kiddies, I am just joking!)
Here they are:
1. Simplify this expression.
2. Solve this absolute value inequality.
3. Solve this system of linear equations.
4. Solve this quadratic equation.
ok, here we go. i better get these right. or i will feel very stupid.
ReplyDelete1. y9/27x3
[y to the 9th over 27 times x cubed]
2. -9 greaterthanorequalto x greaterthanorequalto -1
3. (-2,3)
4. This is the one that I can't figure out....!?!
-1 plus/minus squarerootof 65 all over 2
or... 3.53 or -4.53
I'm sure that's wrong, but I just finished my Chem2 final, you can't expect too much outta me.
Nope!
ReplyDeleteHa, ha, ha!
i feel stupid
ReplyDeleteI'll give a try (my trig final is done).
ReplyDelete1) y to 9th power over 9 times x to the 3rd power
2) x is greater or equal to -1 and less then or = 9
3) x=-2, y=3
4) -5 + or - radical 65 over ten. (and i don't know what that is simplified).
The weird thing about math, is that it's rather relaxing. I can't cram one more spanish word or english poet into my head, but math is just like solving a puzzle. Its taking a bunch of random pieces and fitting them all together to make one simple equation!
Matt,
ReplyDeleteI can't do it. I don't know how to put thoswe expressions in the Google calculator. Besides, I majored in Psychology. We don't need no stinkin algebra in psychology; well, at least I don't. :-)
Which buttons do I press on the calculator for those questions?
ReplyDeleteI would try, but I had my algebra II exam yesterday (yuck) and so I'm all mathed out.
ReplyDeleteWell, I think that Tirzah got it right. I will have to double check my answers, but I think that Stephanie made the "commom error" on the last one.
ReplyDeletewhat tirza said
ReplyDeleteI'm feeling very, very old right now. Can it possibly be decades since I even looked at such things???
ReplyDeleteOooh, check if i got it right? were these on like the Alg. 2 final or what?
