Answer 12

Are you going to post the problem?

Answer 13

can i post question and you give me the answer

Answer 14

You're asking the community to do quite a bit of work for you to just post the solution outright on a linear algebra problem.

Answer 15

\[determine is w = \left[ 1 3 -4 \right] is \in null A,wheer A=\]

Answer 16

as i told you i am a dull student in maths

Answer 17

You can't make it to linear algebra being a dull student!

Answer 18

i cant under stand any thing how to solve if you can't help then its ok no one has time to teach atudent like me

Answer 19

Sorry, I don't understand the problem you posted.

Answer 20

Do you have to find nullspace or the nullity?

Answer 21

its a question of my book david c lay but its not written correctly

Answer 22

null space

Answer 23

Are you finding the nullspace of a matrix?

Answer 24

trying to

Answer 25

ok, one sec my linear algebra book is next to me

Answer 26

oh great
sister if i pass this course i iwll send you a gift

Answer 27

thsi is the question

Answer 35

3 -5 -3 | 0
6 -2 0 | 0
-8 4 1 | 0

So, we need to find the solution for when the system is homogeneous to find the nullspace.

Answer 36
