you want to make a guess?

A

Do you know what absolute value is?
misty1212
  • misty1212
ok answer @mathstudent55 question first
mathstudent55
  • mathstudent55
|0| = 0 |positive number| = positive number |negative number| = positive number
FUZZYBALL
  • FUZZYBALL
no i dont
mathstudent55
  • mathstudent55
The absolute value of a number is just the number with no sign. If the number was positive or zero, the absolute value is just the number. If the number was negative, the absolute value is just the number without the negative sign, so it is a positive number.

The lines represent the absolute value. So for instance, if you had thr number -5, the absolute value of -5 would be 5 since absolute values cannot be negative.
mathstudent55
  • mathstudent55
Examples: |1| = 1 |0| = 0 |-3| = 3 |-25| = 25 \(|\sqrt 2| = \sqrt 2\) \(|-\sqrt 3 | = \sqrt 3\)

  • anonymous
@mathstudent55 is correct.
mathstudent55
  • mathstudent55
Do you understand the absolute value now?
FUZZYBALL
  • FUZZYBALL
I think so..
mathstudent55
  • mathstudent55
Good. Now look at choice A. |-4| < 4 We are comparing |-4| with 4 What is |-4| equal to?
FUZZYBALL
  • FUZZYBALL
4?
mathstudent55
  • mathstudent55
Correct. That means the statement in A is really 4 < 4 Is 4 less than 4?
FUZZYBALL
  • FUZZYBALL
no
mathstudent55
  • mathstudent55
Correct. That means statement A is false. We move on to B.
mathstudent55
  • mathstudent55
B. |–1| < 0 What is |-1| ?
mathstudent55
  • mathstudent55
Correct. A. 1 < 1 Is that true or false?
FUZZYBALL
  • FUZZYBALL
false
mathstudent55
  • mathstudent55
Correct. Move on to C.
FUZZYBALL
  • FUZZYBALL
C is true because 6=6
mathstudent55
  • mathstudent55
C. |–6| = –6 What is |-6| = ?
mathstudent55
  • mathstudent55
Not so fast. What is |-6| = ?
FUZZYBALL
  • FUZZYBALL
6
mathstudent55
  • mathstudent55
That means C really is: |–6| = –6 6 = -6 Is 6 equal to -6?
FUZZYBALL
  • FUZZYBALL
OH no
mathstudent55
  • mathstudent55
Correct. By the process of elimination, the answer has to be D, but since we are not lazy, and we are here to learn, we will look at D.
mathstudent55
  • mathstudent55
D. |–14| > 10 What is |-14| = ?
FUZZYBALL
  • FUZZYBALL
14
mathstudent55
  • mathstudent55
Correct. D is: |–14| > 10 14 > 10 Is 14 greater than 10?
FUZZYBALL
  • FUZZYBALL
yes
FUZZYBALL
  • FUZZYBALL
Thank you so much for your help
mathstudent55
  • mathstudent55
Excellent. D is the correct answer since it is the only true statement among the choices.
mathstudent55
  • mathstudent55
Great job!
FUZZYBALL
  • FUZZYBALL
can you help me with a few more and check one i have already done?
mathstudent55
  • mathstudent55
Yes, I have about 10 minutes I can help
FUZZYBALL
  • FUZZYBALL
ok
FUZZYBALL
  • FUZZYBALL
What is |–12|? i put 12
mathstudent55
  • mathstudent55
Correct
FUZZYBALL
  • FUZZYBALL
Which list of values is ordered from least to greatest? A. |–5|, 0, 3, –|–4| B. –7, –|–3|, 0, |–4| C. –|6|, |–3|, 1, 4 D. |–12|, –|–5|, 2, |–8|
mathstudent55
  • mathstudent55
Remember, the absolute value is only the number without a sign, so if the number is zero or positive, it's just the number. If the number is negative, just take out the negative sign and make it positive.
mathstudent55
  • mathstudent55
Take each choice and rewrite it by writing the correct absolute value. Here is A. A. |–5|, 0, 3, –|–4| 5, 0, 3, -4 |-5| = 5. You understand this, I'm sure. Do you understand why -|-4| is -4?
FUZZYBALL
  • FUZZYBALL
yes because -I-4I it has and extra -
mathstudent55
  • mathstudent55
|dw:1441129271075:dw|
mathstudent55
  • mathstudent55
Exactly. See figure above.
mathstudent55
  • mathstudent55
Since a negative number is less than a positive number, the -4 at the end cannot be in order from least to greatest, so A. is not the answer.
mathstudent55
  • mathstudent55
Now let's look at B. B. –7, –|–3|, 0, |–4|
mathstudent55
  • mathstudent55
-7 and 0 are done. What is -|-3| = ?
mathstudent55
  • mathstudent55
Great job again!
mathstudent55
  • mathstudent55
It isn't but let's look at it. C. –|6|, |–3|, 1, 4 -|6| = -6 |-3| = 3 Ok so far?
FUZZYBALL
  • FUZZYBALL
oh they tricked me :/
mathstudent55
  • mathstudent55
That means C is -6, 3, 1, 4 3 > 1, so it is not in order from least to greatest.
mathstudent55
  • mathstudent55
Right. They try to trick you and you need to outsmart them with your knowledge of math.
FUZZYBALL
  • FUZZYBALL
ok do you have enough time for one more?
mathstudent55
  • mathstudent55
D. |–12|, –|–5|, 2, |–8| Here you can tell it's not it just by looking at |-12| The first number is 12, so this is not possibly in order.
mathstudent55
  • mathstudent55
No, sorry, gtg.
mathstudent55
  • mathstudent55
I'll be back in about 15-20 minutes.
FUZZYBALL
  • FUZZYBALL
okay thanks for your help!
