Hey guys, it's Amelia! Today in math we learned about solving word problems. We learned about the different stages to solving the word problems, and then being able to apply those stages to different types of word problems. The four stages to solve a word problem is; Step 1: Introduce the variables to represent the unknown values (its your let statement) Step 2: Form system of equations involving the variables. Step 3: Solve the system. Step 4: Answer the problem and check the solution! Here is a video to show an example of this for a number applications word problem, Now here is a video to show you an example of a money application word problem. The next video is an example of distance, speed(rate) and time word problem. The last kind of word problem example we went over today was a mixture problem using a system of equations. I hope these examples helped you all understand how to solve word problems better!

Hi diddly ho, matherinos! It's your friendly neighborhood front row classmate! Ya gurl, Katie. I got some rippin' radtastical ways to show you the elimination method!So first, you're gonna stack up your terms like waffles. Like so. <-- So, after plugging your X variable into one of the original problems, you can use your sickass algebra skills to find Y! Alrighty! You should have your coordinates! Nice! Your work here is done! YEET. BUT WAIT! WHAT IF ONE OF MY TERMS AREN'T THE SAME?Don't worry b, i got you.
Also here's a comic for yall about what happened on Thursday haha
Hello it's Frida and here's a quick review. System of linear equations are more then one linear equation. There are three ways to solve systems with two variables, but so far we have only looked at two. The first is graphically, which means that you get the solution by graphing each line. The point of intersection represents the solution. When two lines cross the number of solutions is 1, when two lines overlap the number of solutions is ∞, and when two lines are parallel the number of solutions is 0.
Hi everyone it's Amy. Today we learned about the equations for horizontal and vertical lines. It's pretty simple, for a horizontal line, the slope=0. Therefore, it has a y-intercept of (0,b). Meaning that x is always 0 and y can be anything, y=b. A vertical line, is when the slope=undefined. Therefore, it has an x-intercept of (a,0). This means that x can be anything and y is always 0, x=a. Another way to remember is that when you have the y-intercept it is always horizontal and when you have the x-intercept it is always vertical. Remember that these values go to infinity unless there is a limit on it. For the last 30 minutes we had a work block. Remember that after we are done this unit we are doing a couple days of course review, then we are voting for the next topic! And when you're picking which one make sure you hear Mrs B in your head saying "they wanted to fricken pull red balls out of bags." and vote for something interesting! Hey guys it's Alex with Friday's blog post on lesson 6.6 - Linear Equations: General Form. On Friday we learned how to do general form. The equation for general form looks like Ax+By+C=0. Just remember that you must have a zero on one side of your general form equation. There are also some rules that go along with general form like A,B,C must be integers and A is a positive. When writing down your general form your x goes first, then your y, then your regular number. For example, if y=7x-9 you need to take the y and move it to the other side making your equation 0=7x-y-9. If any of this was confusing or you're just looking for some more help here are a few videos that could help you. Also at the end of class Katie, Nathaniel, and Morgan all showed the class that they had good "cheat codes" for certain equations on desmos. If you would like to know what those are and how to use them. I'm sure they would be happy to help you!!!!
Have a great weekend everybody!! only a few week left of school until summer!! |
