Is the system consistent or inconsistent? y=-1/2x-1 and y=3x+3
which is the first equation? its not completely clear \[y =\frac{-1}{2x-1} \text{ or } y = \frac{-1}{2x} -1\]
Honestly, I don't know. It's typed out exactly how I posted it.
My best guess would be the second equation that you posted.
neither of them are inconsistent
i'll explain how in just a minute
ok, so inconsistent means that there are no values of y or x that satisfy those equations, in effect we cant solve them because we will end up with something silly like 0 = 3
1/2 x (half x) is also possible...
where is this question from? its not very clear what it means
From my homework.
what kind of level maths is it if you dont mind me asking? i could guess at what the equations are because they are of different difficulty
Algebra 1
hmm im not sure... :/
usually we talk about linear equations being inconsistent
The answer was consistent, haha. I got it right.
so maybe we mean: \[y=-\frac{1}{2}x-1\]
-1/2 x - 1 = 3x + 3 -3 1/2 x = 4 x= - 4/3 1/2 -4 * 2/7=-8/7 x= - 8/7 y= 3x + 3 y = 3 (-8/7) +3 y =-24/7 + 3 y= -3/7 Do you have an option similar to those values?
That system is consistent (if that is what it is)
