This week we had one lesson on chapter 7.6 but the rest of the week was dedicated to tests and review. So of course, I’m doing my blog post on that one lesson we had. The lesson was on real life applications of rational equations, like attempting to figure out the time it takes one person to cut the lawn, using the given facts like; the time it takes him and a friend to cut the lawn and the time it takes the one person’s friend to cut the lawn. Once again I’m doing it on paper, so here you go:

If it’s too hard for you to read, which it most likely is, feel free to click it to open it up. Or right click and select open in new window/ new tab. You should be able to read it then

This week we had a unit test for unit 8, we just finished the unit and we’re now moving on to unit 7. So we have a new challenge ahead of us. Once again, I’m using paper instead of MS paint, and $latex, so if it’s it is too small for you to read, feel free to click it to open it up in this window, or right click it to open it up in a different window. We were moving on to Rational expressions so that’s what I did, here ya go:

This week we learned how to solve absolute value equations, we plotted a bunch of them on graphs too. This was some what difficult but a bit easy? I guess would be the best way to put it. Either way, here it is, my attempt at explaining it. Also, once again I’m using paper, not MS paint, or $latex. Here we go:

Once again, if you can’t read it currently you should try and right click it to open it in a new window, or just click it to open it in this one.

This week we learned about solving equations by plotting them onto a graph. This one was pretty difficult, but it’s basically the same stuff as we’ve been doing the majority of the year. So I’m going to try and explain it to the best of my abilities, using Paper, not MS paint or $latex. Here goes nothing:

Once again, if you can’t read it, you could open it up on a new page using the right click, or open it up replacing this page by just clicking it. Feel free to do whatever you fancy.

This week we learned about solving quadratic inequalities. I am still not very good at Math, but do try my best to get all this done, so here’s my best attempt at it. Once again I’m using paper not, MS paint or $latex. And once again if it’s too hard to read within the post try clicking it to make it open up in a separate page.

This week was mostly review for the Mid term, so there wasn’t any new lessons. So instead I’ll go over something from before. It’ll help me get a better understanding of the material. So I’m going to be going back to Chapter 4.7ish where we went over how to Model Problems with Quadratic functions. Once again I’m using paper instead of the $latex thing, and instead of the whole Microsoft Paint. Either way, here you go:

For this week we learned further about how to manipulate parabolas and their different forms. We learned about Standard form, General form, and Factored form. We learned about how the different numbers affect the parabola and we learned about how to convert between the forms. Once again, I plan on doing all the work on actual paper and taking a picture of it and putting it in here. I won’t be using $latex or anything like that.

If this is hard to read just right click it and open it into a different tab. That way, it’ll be clearer.

This week we learned about the different ways to affect and the ways that changing certain things about it changed the parabola we had. We did some Paraboics, which were somewhat fun, and helped me learn how the different numbers affect the pattern in the parabola and the vertex. Either way, let’s get in to showing you what I know. I chose again to do this on paper instead of using $latex or anything else.

If the picture above is too difficult to read in this form, right click it, open it in a new tab and read it there. Sorry it’s low quality.

This time we learned about how to graph linear equations, this wasn’t that hard to get the hang of, and was pretty fun to do in the right way. I enjoyed doing the “Green Globs” activity, and found it to be pretty easy. Now, graphing linear equations works like this, you’ll get something like: y=-5x+10 and you’ll have to graph that. I decided to use paper instead of $latex, sorry if this is hard to read.

Now just in case you couldn’t read some of it, here’s what the top bit says:

y=-5x+10

-5= The Slope

The slope shows the way the line goes (Bottom left to top right if positive and top left to bottom right if negative) and it shows the angle of the line, like how slanted it is.

+10 = Y intercept

The Y-intercept shows you where the line interjects with the Y axis. This is more or less the start point for graphing Linear Equations.

This one is actually on time, unlike the last ones. Sorry about that, but I’ll show you what I know about Quadratic Formulas this time. So in this picture I show the Quadratic formula and attempt to show you how to use it to factor Quadratic Equations.
