Question

Please help someone
Solve the system of equations by graphing then classify the system
5x - 5y = -15
5y - 5x = 15
what is the solution of the system? select the correct choice below

a. the solution is --- type an ordered pair
b. there are infinitely many solutions --
c. there is no solution ---

Is the system consistent or inconsistent?

Are the equations dependent or independent?

Answer 1

C

Answer 2

The system is inconcistent

Answer 3

when one equation is dependent or independent?

Answer 4

not understanding the equation part so does this mean it is independent if the system is inconsistent

Answer 5

my ti83 matrix gives me:

1 -1 | 3
0 0 | 1

but

5x -5y = -15
-5x +5y = 15 <- *-1


5x -5y = -15
5x -5y = -15
-------------
they are the same equation

Answer 6

meaning there is no solution, inconsistent and independent

Answer 7

there are infinitely many solutions since every point of both lines matches at every concievable place

Answer 8

i cant recall the vocab for consistent and dependant tho

Answer 9

thanks a system of equations is consistent if it has at least one solution and equations are dependent if the system has infinitely many solutions so i guess i just answered my question huh that would be consistent and dependent

Answer 10

amistre64
could you lead me in the right direction on a graph whereabout the equations would be marked

Answer 11

amistre64 can you help with this one i lost my way somewhere in trying to solve and graph the compound inequality
7x + 8 > or = to - 48 or 5x + 2 > or = to - 8
the solution of the compound inequality is
{x|x>=to ---?
