Question

What are the solutions of the compound inequality? Graph the solutions. –2 < 4x – 10 < 6

Answer 1

–2 < 4x – 10 < 6
1. add 10 to all the 'terms' like this
–2 + 10 < 4x – 10 +10 < 6 + 10
What do you get?

Answer 2

8<4x0<16

Answer 3

8<4x<16 ...
Now, divide all the 'terms' by 4, like this
8/4 <4x/4 <16/4
What do you get?

Answer 4

2<x<4

Answer 5

That's the answer, I suppose :P
Now, do you know what/how should you graph it? number line? or ..?

Answer 6

yes i do:)
| x | + 10 = 1 will u help me with this?:)

Answer 7

Probably the last question I can help...
first, subtract 10 from both sides. what do you get?

Answer 8

i will only have one more after this.....
and x+0=-9

Answer 9

You need to know that x+0 =x , so you don't have to write '+0' or '-0'
and also you need to keep the absolute sign...
|x| = -9
Absolute value means that we just consider the +ve form of a number.
For example x = 3
|x| = |3| = 3
x=-3
|x| = |-3| = 3
In this case
|x| = -9, which does not make sense...

Answer 10

so whats the answer

Answer 11

No solution :|
Or you can check the question again to see if |x| + 10 =1 is really your question..

Answer 12

ok this is my last one

Answer 14

Hmm... you missed something in the question...

Answer 15

x+6 is greater then or = to 5 sorry;)

Answer 16

Never mind :)
Let this sign ≧ be greater than or equal to ...
x+6 ≧ 5
Subtract 6 from both sides, what do you get?

Answer 17

x(ge)-1

Answer 18

\[\ge\]

Answer 19

Yes. Finished :D
