Thank you , i'm waiting

Answer 3

thats alot of questions, were are you stuck at?

Answer 4

That IS a lot of questions... on matrices too... not my forte, but let's see what I can do.... first, pick a question :)

Answer 5

i like 7 and 8 ....

7 is simple, if det(B) not= 0, its independant and a basis

8 is just solving; Bx = (3,0,3)

Answer 6

of course 9 is the simplest of all, just let B = what it says, lol

Answer 7

I stuck in 6 & 4

Answer 8

Sorry for my late , i was very busy 2 day

Answer 9

well then, 6 has you use the inverse you found in 5 ... what is your inverse from 5?

Answer 10

4 is the same idea, use the inverse that you found in 3, since you did not get stuck in 3

Answer 11

\[Mx=b~\to~x=M^{-1}b\]

Answer 12

inverses can be more easily determined using an augment rather than the cofactor matrixes ...

Answer 13

I don't undrstand it 😞

Answer 14

Any help 😫, 4& 6 linear system

Answer 15
