Best ResponseYou've already chosen the best response.0plug in 3 for c, what do you get?

Best ResponseYou've already chosen the best response.0right, the value of the expression inside the absolute value is 14. But, what does absolute value mean?

anonymous

Best ResponseYou've already chosen the best response.0examples of absolute value x=x z=z 100=100 345=345 etc etc etc

Best ResponseYou've already chosen the best response.0Absolute 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.

Best ResponseYou've already chosen the best response.0o ok so the "3" is just a 3 and not a "3 " so the answer would be 14

Best ResponseYou've already chosen the best response.0You are half right...

anonymous

Best ResponseYou've already chosen the best response.0"3" is still 3. That doesn't change. The problem says that c = 3. So, c = 3

anonymous

Best ResponseYou've already chosen the best response.0But, the problem says that you have to find /4c2/ when c = 3

anonymous

Best ResponseYou've already chosen the best response.0So, 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.

Best ResponseYou've already chosen the best response.0o ok thanks man were did you get the ? /12/ + /14? ?

anonymous

Best ResponseYou've already chosen the best response.0Where did I get 12???

anonymous

Best ResponseYou've already chosen the best response.012 is the product of 4 and 3

Best ResponseYou've already chosen the best response.0When you plug in 3 for c, you multiply 4 x 3

Best ResponseYou've already chosen the best response.0o i see now wow xD thanks man for all of your help

anonymous

Best ResponseYou've already chosen the best response.0You'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

anonymous

anonymous

Best ResponseYou've already chosen the best response.0Oh I see, I was simply using the same notation as "sup"

Best ResponseYou've already chosen the best response.0Isn't there a keyboard shortcut for superscript too? Might come in handy for exponents

Best ResponseYou've already chosen the best response.0i am stuck on this one /10z,/z =3

Sup_open~study

Best ResponseYou've already chosen the best response.0but i think it is wrong

anonymous

Best ResponseYou've already chosen the best response.0Ok, rewrite the expression after plugging in z = 3

anonymous

Best ResponseYou've already chosen the best response.0Also, use , it's the key above the enter key. You must use the shift key

Best ResponseYou've already chosen the best response.0/10 (3)/ like that ??

anonymous

Best ResponseYou've already chosen the best response.0Nope, you are using /. Press shift and \

Best ResponseYou've already chosen the best response.0lol you're teaching people already @teic85

anonymous

Best ResponseYou've already chosen the best response.0And no, the expression is missing a minus

Sup_open~study

Best ResponseYou've already chosen the best response.0i no clue what the shift thing is lol xD

anonymous

Best ResponseYou've already chosen the best response.0lol yes @Hero, that's the purpose of Open Study right? :D

Best ResponseYou've already chosen the best response.0haha ok, @Sup_open~study . Let's focus on the problem first.

Best ResponseYou've already chosen the best response.0i think i am so post to  it and not x it ?

anonymous

Best ResponseYou've already chosen the best response.0Correct, you have to subtract z not multiply You wrote /10 (3)/ The original expression is 10z

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0Be careful, you also missed the negative in front of the 10

Sup_open~study

Best ResponseYou've already chosen the best response.0o i see yeah i was writing it wrong xD

Best ResponseYou've already chosen the best response.0Rewrite the expression after plugging in 3 for z

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0z = 3, but the expression is 10 MINUS z. So, it should be 10  (3) which is actually 10 + 3

anonymous

Best ResponseYou've already chosen the best response.0What is 7? You are jumping ahead... :)

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0When you plug in 3 for z, you get: 10  (3)

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0That look about right to you?

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0Ok, so we know that minus 3 is actually +3. So rewrite the entire expression with +3 in that spot

Sup_open~study
 3 years ago
Best ResponseYou've already chosen the best response.0ok so it's 10  (3)

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0Not quite, Minus 3 is +3. So, it is 10+3

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0a negative and a negative make a positive

Sup_open~study

Best ResponseYou've already chosen the best response.0o i see but how would i solve that ??

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0ok, well now that that pesky z is gone, we can just focus on what is inside the absolute value. What is 10 + 3?

Sup_open~study

Best ResponseYou've already chosen the best response.0 7 so it's just 7 ?

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0The absolute value of 7 is 7. Yes.

Sup_open~study

Best ResponseYou've already chosen the best response.0o ok i see now but on the answer for the study guide he put 7 why not 7 ??

anonymous

Best ResponseYou've already chosen the best response.0What's in front of the absolute value?

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

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0This is the expression: 10+3. What is in front of the absolute value?

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0So look at this... 7 = 7 What is 7 ?

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0Since the negative sign is in front, it makes the expression negative. So 7 is the answer.

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.07 is different than 7

Sup_open~study
 3 years ago
Best ResponseYou've already chosen the best response.0o so it's just 7

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0The expression in your problem has a negative in front like this, 7

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0So, the absolute value of 7 is 7. But, then you have to add the final negative (the one in front). So, it's 7

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

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0Don't think "most likely". You'll get the wrong answer. That's just guessing.

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0Think about this... what is 2(1 + 3) ?

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0Right. The negative in front changes it to negative. So, when you have a positive number times a negative number you get a negative.

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

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0The 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)

Best ResponseYou've already chosen the best response.0o i see thanks man you have been a huge help i may have failed my test tomorrow if it was not for you

anonymous

Best ResponseYou've already chosen the best response.0I'm glad to help. Just be careful not to forget negatives. They matter a lot.

Sup_open~study

Best ResponseYou've already chosen the best response.0yeah i know i got to keep on practicing those xD

anonymous

Best ResponseYou've already chosen the best response.0Exactly. If you practice, you'll get more comfortable. Eventually, you'll be able to do it in your head :)
