My top 5 most important things in math 10

1. learning how to do linear equations.

learning linear was the most important to me in my top 5 because that is what I most remembered and I think the most useful to use in the future in math 11 and 12.

2. sitting with people

sitting with different people each unit not only help us understand and know one another, but also get us communicate and help each other in math problems and deepen friendship.

3. Pythagoras theorem

this is handy to know if you are doing anything with triangles. It can find a missing side of a right triangle if you have 2 of the 3 sides. a² + b² = c²     

4. Ms. Burton’s Acronyms

ms burtons funny acronyms always helped me in tests and had and will always remember it.

an acronym: King Henry Doesn’t Usually Drink Chocolate Milk

stands for: Kilo, Hecto, Deca, Unit, Deci, Centi, Milli

another one: BFSD which is Best Friends Share Deserts

and stands for Brackets, Fractions, Simplify, and divide

5. A fun math class

in all math classes I have been in, ms burton always made it fun and entertaining everyday for her students. she always had something in advance and explained things thoroughly. she had things like fraction Friday and Meaningful Monday to help us study for tests. she was always there to help student at mornings and after school.

that is all I had for my top 5 of the week! going to miss math 10 and hope I will have ms burton as my math teacher again.

this week we did system of linear equation substitution and elimination.

System of linear equation is where you take two sets of linear equation and trying to find the point on where would they cross or meet.

to solve this system you could either substitute or eliminate. Substitution is where you take one set of equation and try to isolate a variable and then insert that on where your isolated variable is on the other set of equation to find the value of that variable. And also do this vise versa to the other variable to get the value.

The elimination method you either add or subtract the equations to get an equation in one variable. You have to “cancel out” one variable to get the other variable, after you insert what you got into one of the set to get the other variable and now you have the coordination of  where the linear would meet.

For this one I used elimination and subtracted from both equation the 3y and from there on I had the answer x=4, then I inserted it to one of the equation to where there would be an x to replace it and solve that equation and I had an answer of y=2. So the coordinate they would meet or cross is in (4,2).

that is what we learned this week on systems of linear equations.

That week we learned how to interpret graphs of functions and to do distance formula.

interpretting graphs is explaining what is happening in the graph by how and what the slope looks like. When it is a flat line it is a constant rate, if it is going up your increasing and going down is decreasing.

for example

,

When I was walking home, I walked at a constant rate, then slowed down and and walked at that rate, then started walking again at a faster rate for a short while then walked at a constant rate till I slowed down to stopped at my doorstep.

this is how you interpret a graph function and how to do it.
