Algebra With Mr. Dorman
Algebra is one really hard class! Thankfully my teacher Mr. Dorman helps me to understand it. During my algebra homework we are asked to watch videos at home on Mr. Dorman's website. Each video we are required to take notes and bring them to class the next day to review and look over what we didn't understand. At first this concept was interesting for me because I had never done anything like it before. After a while, though, I started to understand and get the concept. This class most likely relates to my computers class because we are asked each night to watch videos on our devices or computers. I really enjoy taking this class and hope I can keep learning more and more.
Homework
During this semester, Mr. Dorman has supplied us with a lot of homework. On this page (to your left) it shows a page I did on the area of a composite figure. I found the area by splitting the large complicated shapes into smaller simpler shapes then in the end added all those areas together. For the con-like objects, I found the area of a circle and divided it by two, since we only see half a circle. Then, I found the area of the right triangle and finally, added the two areas together. For number 6, I found the area of a normal rectangle, then I found the area of the half circle and subtracted it from the area of the rectangle. Although it may seem tricky now, if you ask questions and work (and study) hard, you will get it! I know this will one day help me even if I don't see it a lot today.
Linear Equations
Right now in Pre-Algebra I am a little confused. We recently talked about linear equations which is something that took me a while to understand, but I like! Mr. Dorman taught us how to use the equation "y = mx + b" Y is your answer. Its what you get once you've done the rest of the equation. M is you slope. How many did you rise and run from where you see your first point to its following point. X is your variable. It can stand for any number you want. Of course you might want to use the graph to determine that! B is where your line hits the "Y Axis" what number is it touching or closest to? Lets say you have this line graphed like the picture to the left, how can you make an equation out of that?! Well use your equation, y = mx + b. What is "y?" Well, we don't know because you can't get your answer without solving the problem! Ok, what next? What is "m?" Well, "m" is how many you rose and ran. Look at where the line hits the "Y Axis." 2!!! So start at 2 and how much did you go up. Where is the next red dot?! At 2 1/2!!! Now lets plug in our numbers, "y = 2 1/2x + b" GREAT!!! What's "b?!" We technically answered that question! Where does the line touch the "Y Axis?!" At 2! C-o-r-r-e-c-t!!! Now we have, "y = 2 1/2 x + 2!" There is your equation! Incredible! You just solved a linear equation! Good work and practice!
