>Canadian senior high school /mu/tant here.

We have a test tomorrow on 4 plane intersection and matrices. Is there any info I need to know?

Also I can't find any examples of questions I can do to prepare myself for this. Some examples would be great.

One example my teacher gave us was:

2x + 3y + 4z + q = 2
6y - 3z +3q = 34
4x + 4y - 7q = 75
x + y + z - q = 3

Solving that using matrices is easy. Need more examples.

Are there any ways to bolster your math (in general) skills? I seem to be great at everything but math. Something about those multistep problems filled with numbers and letters. Is there anyone here that overcame an academic deficiency in math? If so, how?

How will the equivalence point volume change if you titrate the two solutions. What is the pH of the equivalence point of the two solutions if you titrade with 0.3M NaOH?

The two solutions are a 10ml vinegar solution that has a concentration of 5% (w%/v%) and 10ml vinegar solution that has a concentration of 5% (w%/v%) together with 30ml of water

sure is intelligent in here

Everyone sure has a lot of 'proof' in here...
