(Jaden Zimmerman) Ha!
2.212341345x+(2.23125x-54.123452) = 1

Interesting I had a hard time with this...

Since there is an addition sign before the parenthesis, we do not distribute. We can just combine all like terms.

2.212341345x+(2.23125x-54.123452) = 1
2.212341345x+2.23125x - 54.123452 = 1
4.443591345x - 54.123452 = 1
+54.123452 +54.123452
4.443591345x = 55.123452
/4.443591345 /4.443591345
x = 12.40515783748337

Lots of decimals but not too hard.

Hello!

The very confused Mysterious man nobody knows(Emmett)

10/19/2015 01:04:53 pm

First of all I am NOT Emmett!
Also, can a standard form graph be increasing, or is it always decreasing?

Jack Epp

Good question. I was wondering that too.

Cora C.

10/19/2015 01:21:02 pm

I think it can be both, depending on what the values of the x and y-intercepts are.
That seems like a very interesting game! I might try that!

Mr. Bigsby

10/22/2015 08:17:25 am

Good question Emmett, and great answer Cora. It does depend on the x and y intercepts.

I kind of understand. but not quite.
So I have a question.
Can we figure out the value of BOTH variables rather than having to substitute one of the variables for zero to find the other one?

I now understand after the lesson

Mr. Bigsby

10/22/2015 08:18:50 am

Each line has an infinite amount of (x,y) pairs. If you know one of the variables you can always solve for the other. We just use 0 to help us graph because it is the easiest to solve and plot.
