14 ?

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
is that right ?
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
right, the value of the expression inside the absolute value is 14. But, what does absolute value mean?
 one year ago

examples of absolute value x=x z=z 100=100 345=345 etc etc etc

i'm sorry an you explain more

Do you know the definition of absolute value?

Absolute value is the numerical value of a number without considering the positive or negative sign. So, the absolute value of 10 is 10. The absolute value of 2 is 2. It is just the value of the number. It is always positive.

o ok so the "3" is just a 3 and not a "3 " so the answer would be 14
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
You are half right...
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
Let's back up...
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
"3" is still 3. That doesn't change. The problem says that c = 3. So, c = 3
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
But, the problem says that you have to find /4c2/ when c = 3
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
So, plug in 3 for c just like you did before, /4(3)2/ = /122/ = /14/ So, when you plug in 3 for c, the expression equals /14/. But, the absolute value of 14 is 14.

o ok thanks man were did you get the ? /12/ + /14? ?
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
Where did I get 12???

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
yeah :)

12 is the product of 4 and 3

o i see now wow xD thanks man for all of your help
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
You're welcome. If you have time, try these to make sure you know how to do absolute values: Find /4c2/ when c = 3 Find 4/c/2 when c = 3 Find 4c  /2/ when c = 3

ok awesome man thanks i will do :)

Isn't there a keyboard shortcut for superscript too? Might come in handy for exponents

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
but i think it is wrong

teic85 Group TitleBest ResponseYou've already chosen the best response.2
Ok, rewrite the expression after plugging in z = 3
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
Also, use , it's the key above the enter key. You must use the shift key

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
/10 (3)/ like that ??

teic85 Group TitleBest ResponseYou've already chosen the best response.2
Nope, you are using /. Press shift and \

lol you're teaching people already @teic85
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
And no, the expression is missing a minus
 one year ago

i no clue what the shift thing is lol xD

lol yes @Hero, that's the purpose of Open Study right? :D

haha ok, @Sup_open~study . Let's focus on the problem first.

i think i am so post to  it and not x it ?
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
Correct, you have to subtract z not multiply You wrote /10 (3)/ The original expression is 10z
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
Be careful, you also missed the negative in front of the 10
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
o i see yeah i was writing it wrong xD
 one year ago

Rewrite the expression after plugging in 3 for z
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
/103/ = 13 ?
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
z = 3, but the expression is 10 MINUS z. So, it should be 10  (3) which is actually 10 + 3
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
so it's 7 ??
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
What is 7? You are jumping ahead... :)
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
sorry xD
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
haha it's ok :)
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
When you plug in 3 for z, you get: 10  (3)
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
That look about right to you?
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
yeah thanks :)
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
Ok, so we know that minus 3 is actually +3. So rewrite the entire expression with +3 in that spot
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
ok so it's 10  (3)
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
Not quite, Minus 3 is +3. So, it is 10+3
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
a negative and a negative make a positive
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
o i see but how would i solve that ??
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
ok, well now that that pesky z is gone, we can just focus on what is inside the absolute value. What is 10 + 3?
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
 7 so it's just 7 ?
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
The absolute value of 7 is 7. Yes.
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
o ok i see now but on the answer for the study guide he put 7 why not 7 ??
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
What's in front of the absolute value?
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
i can't tell what you are looking for sorry but he had like a 1 10 + 7 ?
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
This is the expression: 10+3. What is in front of the absolute value?
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
a negative
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
So look at this... 7 = 7 What is 7 ?
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
Since the negative sign is in front, it makes the expression negative. So 7 is the answer.
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
7 is different than 7
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
o so it's just 7
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
No, it isn't just 7.
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
The expression in your problem has a negative in front like this, 7
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
yes
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
So, the absolute value of 7 is 7. But, then you have to add the final negative (the one in front). So, it's 7
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
ok so when you have the  in front of the problem the answer is most likely going to be a  ???
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
Don't think "most likely". You'll get the wrong answer. That's just guessing.
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
Think about this... what is 2(1 + 3) ?
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
Right. The negative in front changes it to negative. So, when you have a positive number times a negative number you get a negative.
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
o i see so when you change the answer to positive the negative will times it and that will make it an negative ?
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
The same is true for absolute values. The negative in front of 7 is like multiplying 1 times 7 (what your teacher had in your notes)
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
o i see thanks man you have been a huge help i may have failed my test tomorrow if it was not for you
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
I'm glad to help. Just be careful not to forget negatives. They matter a lot.
 one year ago

Sup_open~study Group TitleBest ResponseYou've already chosen the best response.0
yeah i know i got to keep on practicing those xD
 one year ago

teic85 Group TitleBest ResponseYou've already chosen the best response.2
Exactly. If you practice, you'll get more comfortable. Eventually, you'll be able to do it in your head :)
