Question

Make a conjecture about the solution of a system of equations if the result of subtracting one equation from the other is 0 = 0
a.
there are no solutions
c.
cannot determine any solution
b.
there are infinite number of solutions
d.
the solutions are inverses of each other

Answer 1

Im thinking its C. Cannot determine any solution..

Answer 2

No never mind its A there are no solutions because its inconsistent

Answer 3

If the result is 0 = 0 it means the two equations are identical.

That means infinite solutions.

Answer 4

back from window shopping already? that was fast O.O

Answer 5

Remember the difference: a nonsense answer (like "0 = –2" in the previous problem) means an inconsistent system with no solution; a useless answer (like "0 = 0" above) means a dependent system where the whole line is the solution.

lol @sourwing I have to finish my class or ill fall behind

Answer 6

wth? it's only 3 days before christmas and you're still in school?

Answer 7

no I didn't finish my math before the semester ended because I had some family issues so I have to Finish it now or ill fall behind

Answer 8

If you get 0 = -2 then it is inconsistent and therefore, no solutions.

Here they are saying you get 0 = 0.

Example:
2x + y = 4
2x + y = 4
Subtract and you get
0 = 0

There is just one equation and two unknowns. That means infinite solutions.
pick x = 0, then y = y
pick x = 1, then y = 2
...
etc. infinite solutions.

Answer 9

Awesome thank you so much!

Answer 10

You are welcome.

Answer 11

well good luck lol

Answer 12

yeah I'm pretty close I'm at lil 75% only 25% left to go lol
