Answer 1

A

Answer 2

umumum

Answer 3

me?

Answer 4

show your solutions or I'll have you banned for giving out answers

Answer 5

or him

Answer 6

me or him...im scared now

Answer 7

i got b when i worked it ut i was just asking if it was correct

Answer 8

All the same... how DID you get b?

Answer 9

1-6 =-5 rite ????

Answer 10

is the answer given wrong????

Answer 11

thats what my calc

Answer 12

no one is allowed to give out answers @vivek4607 coocoobird

Answer 13

@vivek4607 no giving away answers, like nin stated

Answer 14

...
it would be useful to point out that you, @dirtydan667 , are not currently dealing with an equation, but rather, an inequality, and a STRICT inequality, at that (>, not \(\ge\))

Answer 15

it would be x-6<y, and -6-x>y (i think :P)

Answer 16

um um um um um um um um im scured

Answer 17

@nincompoop ...dude...she just asked for the solution...not for the how solution comes....better read the question first....:)

Answer 18

who she

Answer 19

Solution = Answer... and...

Answer 20

ohk...thanx for reminding me...:)

Answer 21

wait im confused what is the awnsere

Answer 22

@dirtydan667
Listen up...
to know if a point is a solution of an equation (or an inequality) just plug everything in and see if it all checks out.

Here's an example... try the point \((\color{red}3,\color{blue}6) \)


\[\Large \color{blue}y > |\color{red}x|- 6\]Plug in...
\[\Large \color{blue}6 > |\color{red}3| - 6\]
Simplify...
\[\Large 6 > -3\]
Which is true... so, the point \((\color{red}3,\color{blue}6) \) IS a solution. Now try with your actual choices.

Answer 23

y > |x| - 6
y+6>|X|
y+6=x OR y+6=-x
y+6=x or -y-6=x
by putting all the values of x and y given u can find out ur answer

Answer 24

so A ?

Answer 25

u can check it....:)

Answer 26

so B?
or maybe even C?

Test it.

Answer 27

try to SOLVE it

Answer 28

you don't want to be banned for soliciting answers now

Answer 29

so it is a 1>-1

Answer 30

Where did that come from? D:

Answer 31

i enterd the points from A

Answer 32

Show.

Answer 33

kk one sec

Answer 34

eyes are unto you, coocoobird, you better show your solution or just close this post and move on

Answer 35

um ok first i enterd the points in a then did the || then i got 1>-1

Answer 36

whats so hard to beileve

Answer 37

eh? that's not a solution :) if you've read terenz' example, then you would do the same format for your solution. c'mon, man, you can do this…. this question is beneath your ability

Answer 38

no its not the soultuion but it means a is correct

Answer 39

I wouldn't know until you start plugging in values

Answer 40

No @vivek, y+6>|X| is NOT equivalent to y+6=x OR y+6=-x

An abs value inequality does not become a compound equality.

think about what is means that: y+6>|X| It means that the DISTANCE of X from 0 is less than y+6. Therefore:

-(y+6)<x<(y+6)

or as two separate inequalities you have:

-y-6<x and x<y+6

Now if you didn't simply have points to check, you would solve each, and take the INTERSECTION as your solution set. This can be illustrated graphically by graphing the 2 lines in the x-y plane and shading in the area where all the points make both inequalities true.
