Question

Describe and compare the solution set of xsub1+5xsub2-3xsub3=0 and xsub1+5xsub2-3xsub3=-2.

Answer 1

inconsistent

Answer 2

compare wid wat ?

Answer 3

that is the question

Answer 4

@ganeshie8

Answer 5

hmm, then i would describe it as, they're parallel planes with out any common elements in their solution sets. the solution sets are disjoint

Answer 6

What is a homogenous linear system?

Answer 7

Ax=0

Answer 8

there will always be a trivial solution : x = 0

Answer 9

yes, it's no solution

Answer 10

How and why?

Answer 11

you can think of the line or the plane,
If it is a line, how can the same line have 2 values 0 and -2?

Answer 12

the left hand side are the same, right? but the right hand sides are different

Answer 13

yes

Answer 14

mathematically, the matrix (2x4), after take rred, it gives us a line 0 0 0 1 , so we can conclude that the system is inconsistent

Answer 15

why?

Answer 16

dont' see anything

Answer 17

Oh okay nvm

Answer 18

without rref the matrix how would youu know the system is inconsistent?

Answer 19

hey!! you have a matrix. and you don't allow me use matrix method to solve it???

Answer 20

1/ the system have 2 identical equations with 2 different values--> inconsistent

Answer 21

DAT SIT

Answer 22

ohhhhhhhhhhhhh man

Answer 23

wow... light bulb just went off in my head
