Question

Anyone in Keystone National High School Algebra 2? Really need help!

Answer 1

I am, what are you doing now?

Answer 2

Consistent and inconsistent quiz, but pretty much the part two of the Algebra course.

Answer 3

ok so I'll take the first 2 for an example.
1. Is the following system consistent or inconsistent?
8x + y + 4 = 0
y = -8x - 4
that's consistent because it has all the same numbers pretty much.

2. Is the following system consistent or inconsistent?
7x + 6 = -2y
-14x -4y + 2 = 0
that would be inconsistent because it doesn't stay the same and isn't increased by the same factor, does that make sense?

Answer 4

A little can you explain the second one that is inconsistent a little more?

Answer 5

yeah, so the 7x is increasing at a rate of -2, making it -14x, but the -2y is increasing by 2, bot -2. Also, you would have all of the normal numbers like the 6 would all be moved to one side, plus it isn't increased or decreased by -2 or 2, so everything is inconsistently changed. Make more sense?

Answer 6

So, here's another example..
y = 2x + 5
-2x + y = -2
so this will be inconsistent because you're not keeping the 5 a five when y is staying the same and the 2x becomes -2x because you are subtracting it on both sides. the -2 on the right side of the equation would still be 5.

Answer 7

Yes, thank you!

Answer 8

no problem :) let me know if you have other questions in the unit

Answer 9

Okay, just curious are you finished with the course?

Answer 10

I'm in last unit, taking the final tomorrow.
