Question

Classify this system of linear equations.
A. inconsistent
B. consistent, independent
C. consistent, dependent

Answer 1

u have read matrix?

Answer 2

1. x+y=2
x-y=2
consistent and independent

Answer 3

2. x+y=2
2x+2y=4
consistent and dependent

Answer 4

3. x+y=2
x+y=4
inconsistent

Answer 5

it's fine?

Answer 6

10y=5x=35
x=2y-35

Answer 7

let me explain...then u can find it by own....consistent and independent means unique solution

Answer 8

consistent and dependent---infinite solution
inconsistent---no solution

Answer 9

10y=5x=35 ??
x=2y-35

Answer 10

u have wriiten the equation correctly?

Answer 11

10y=5x+35
x=2y-35

Answer 12

5x-10y=35
x-2y=-35
now...compare this with above mentioned three cases..and u can answer it by your own...just try it

Answer 13

simplify it more...x-2y=7
x-2y=-35

Answer 14

now compare this with above three cases

Answer 15

does it look like case 2 ?

Answer 16

consistent dependent?

Answer 17

no....it's inconsistent

Answer 18

case 3

Answer 19

do u know to plot a linear equation?

Answer 20

on a graph yes

Answer 21

i think...today only.....i told u to plot a linear equation

Answer 22

so if u'll plot these two lines then u'll get two parallel lines...which wont intersect i.e. no solution...

Answer 23

i.e. inconsistent

Answer 24

oh yeah alright thanks

Answer 25

anything more?

Answer 26

no i'll be good
