A hole in the graph

Hell0 :)

Today in class, we continued doing the unfinished example from yesterday's class. The first thing we did was Mr. k showed us the video of a real "Plug Hole" because it is related to our topic today. Here's what he showed us "Plug Hole (short version)" "Plug Hole (long version)" Feel free to watch it..

Anyways here are the examples we did...

Reflection

Hello everyone..

To be honest..
I think I'm still not confident for tomorrow's test because I still have some topics that I don't get and when when I look at it I get confused :( . Such as determining the truth or false in Conditional Statement, Contradiction and Counter example. But I hope I'll be able to understand it tonight :)

Also, don't forget to bring your lucky charm...

I'll try to bring one too if I have one eheheh :)

See yah all tomorrow... GOOD LUCK!!!

hello!! everyone...
tomorrow will be our pre-test in geometry and I think I'm ready for it but not in actual test. This unit is kind a hard for me because in order to solve the problem I should know what kind of theorem is it and if I got it right I still have to prove it. Proving and finding the angles are my weakness so I hope I'll be able to work on it before the test...

that's all..
good luck everyone....

Reflection: Analytic geometry Test...

Geometry test..
ahmm,, I think this unit is quite hard for me, especially when it comes to rational inequality but thanks to mr. K I finally understood how to solve it, so I'll do my best on our test. In this unit my favorite topic is the system of equations because I think it is much easier than inequalities. When solving inequalities I prefer to use number line instead of using graph because when I'm using graph it confuse me.. =)
Ok I think that's it...
GOOD LUCK EVERYONE on OUR TEST!!!
aja!! :)

Pre- Test on Analytic Geometry

Hello!! everybody.....

Today in class we did our pre-test but before that, we work on Analytic Geometry #8

here's the question...

8. The total number of known moons around Saturn, Uranus, and Neptune is 43. The total number of moons around Saturn and Neptune is 9 more than the number of moons around Uranus. Saturn has 2 moons more than twice the number of moons around Neptune. Find the number of moons each planet has.


To solve this problem you have to do the following:

• first, you have to find the equation
• Then when you have the equation, set it up so it will be easy for you to solve it.
• Then when solving it, you can use elimination or substitution

here's the equations..

S = # of moons around Saturn
U = # of moons around Uranus
N = # of moons around Neptune

S + U + N = 43
S + N = U + 9
S = 2 + N

Topics that I don't get...

Hello!! Mr. K

here are the following topics that I still have to work on...

• circles and radius problems
• ambiguous triangles
• rational inequality
• absolute value inequality

Completing The Square

hello! everyone this is Ramina :) and I'm the one who's scribing for today's class.

Completing The Square
- is the process of converting a quadratic equation into a perfect square trinomial by adding or subtracting terms on both sides.


For Example:







To explain it properly please just visit these following website:

1) Completing the square m² + 12m + 30 = 0

2) Completing the square 3n² - 4n - 1 = 0

3) Completing the Square



These are the things that we talked about completing the square....
