Answer 1

Can you solve for x? That will make this question more clear.

Answer 2

I don't understand this it would be great if you could give me the answer :/

Answer 3

I'm not here to give you answers. I'm here to help you understand it. Do you have any idea how to solve for x?

Answer 4

no can you help me step by step so i can understand it?

Answer 5

Ok.
\[\frac{-x}{4} \le 2\]

Answer 6

Multiply both sides by 4. That will get rid of the 4 in the denominator on the side with the x.
\[-x \le 8\]

Answer 7

yeah

Answer 8

Now. We need to get just 'x' by itself. So, we need to get rid of that negative sign on the x.
What we can do is multiply both sides by -1.
However, during inequalities (equations without an equal sign), you have to switch the sign when you multiply or divide by a negative number.
\[-x \le 8\]
\[x \ge -8\]

Answer 9

oooooh so that becomes your final answer?

Answer 10

Yes, that is the simplied inequality. And you can figure out what is looks like on the number line. It's every number greater than -8, including -8.

Answer 11

Thanks! Can you help me with this one to http://prntscr.com/39n7wb

Answer 12

It's the similar situation. How can you get z by itself?

Answer 13

Divide?

Answer 14

Divide by what?

Answer 15

4

Answer 16

nvm -32

Answer 17

Try again. There's a negative sign tacked onto 4z.

Answer 18

Yeah that's why i switched

Answer 19

Why would we divide by -32? We're trying to get z all by itself.

Answer 20

\[-4z \le -32\]
We want to divide by -4, not 4, to get 'z' all by itself.

Answer 21

ooh

Answer 22

What does the final answer look like now? Remember, when dividing or multiplying by a negative number, you have to change the sign.

Answer 23

-z\[-z \ge 8\]

Answer 24

You switch it

Answer 25

Try again. Remember, we divided both sides by -4. So there is no more negative sign on the left.

Answer 26

\[z \ge-8\]

Answer 27

Uh, you were closer the first time.
\[-4z \le -32\]

We divide both sides by -4. That will cancel out the -4 on the left side. On the right side, we have a negative divided by a negative, which is a positive. Finally, we change the sign.

\[z \ge 8\]

Answer 28

aww it kind of makes sense now can you help me with some more?

Answer 29

and thanks a lot

Answer 31

You can do this. Get the x term by itself. Divide to get 'x' all by itself.
You don't have to switch the sign this time because you'll be dividing by a positive number.

Answer 32

ok ill try and i will get my answer and tell me if its right

Answer 33

its the 4th one :p

Answer 34

So i divide 5 and get x then do i add 17 with 7?

Answer 35

move -17 to the other side, then its 5x>-10

Answer 36

ooh

Answer 37

then divide by 5 and its x>-2

Answer 38

are we on #8?

Answer 39

yes

Answer 40

#9 is the 4th one

Answer 41

solve for x again

Answer 42

Do you know what 10 is?
