Question

Matrix help! Please help!

Answer 1

This only has one row, so bare with me. The video had two rows.

Basically Going this way is your row -> and going this way ^v is your column.

You're going to want your first element and your last one.

Your first element is -9 and your last element is 1.

So it should be -9 times 1.

Sorry If i'm wrong.

Answer 2

How about the middle numbers?

Answer 3

Well I'm not exactly sure but when they do equations like this, your's only has one row lmao but if you were given \[a~_3~_6\]

You'd look at the the row and then the column. Thats really only what the middle numbers are for.

Answer 4

Middle numbers sort of are used when your given something as such a36 or wtvr. You'll use the row's and columns then. Just as you used it in anyway given.

Answer 5

I think it plays more into this question.

Answer 6

I believe that it's undefined. Lmao, do you see a 2 or a 1 in that matrix?

Answer 7

When you're given two different numbers after those letters, you split them apart and find the row and column which is quite easy considering the first number is your row and your second one is your column. The numbers most likely would have to be in the matrix for it to be solved.

Answer 8

I wanna cry:

Answer 9

I appreciate your help! :)

Answer 10

Okay, lmao so remember what I said earlier with the column's and the rows?

So basically, your rows go left to right ur columns go up to down.

I'm guessing they want B over A? So I suppose it'd be -3+1 over -1+3.
