Homework

Finish yesterday's work if needed.

I am totally confused

The chart didn't have any "=" but it is easy to get hung up on the equations we have been doing. You just needed to change the x into the number for that row, then follow the order of operations.

I couldn't find the ___________ button. Some of our calculators have seen better days. Lots of people have pressed the "y=" button and the "(" ")" buttons so they can be hard to read. Luckily, there isn't a self-destruct so press button! "Clear" or " "2nd" then "Mode" will get you out of anything!  This is an image of the calculator if that helps.

What are we even doing?

Why are we doing this? So we can do this, which is very useful in many jobs you might do someday.

  1. I'm still confused! I wasn't sure what you were doing, and now I'm working on my study guide and? I can't tell what kind of solution it's going to have by just looking at the answer..

    1. Ok, there are three options for how the answer looks.
      variable=constant
      Something that is true
      Or
      something that is a lie

      Which is yours? If you cant tell, then post you answer.
