I have a few more questions
fouzberzerk
  • fouzberzerk
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|
anonymous
  • anonymous
all you need to know to solve these questions is that |-a|=a |a|=a
anonymous
  • anonymous
apply that rule of modulus and you should solve it
fouzberzerk
  • fouzberzerk
Can I get some help besides that? I'm clearly having issues understanding.

|-10| mean that how far the value is from zero so from this instance its 10 units, so basically drop the negatives signs.
anonymous
  • anonymous
yep so |...| is simply called the 'modulus of what ever is in between these vertical lines so all we do is take the positive number inside the lines
anonymous
  • anonymous
the value for |1| is simply the positive value of 1, which is 1. the value for |-1| is simply the positive value of the number, which too is 1
fouzberzerk
  • fouzberzerk
That doesn't apply too the question above though.
fouzberzerk
  • fouzberzerk
|–5|, 0, 3, –|–4| B. –7, –|–3|, 0, |–4| C. –|6|, |–3|, 1, 4 D. |–12|, –|–5|, 2, |–8| None of the first numbers are the smallest.
fouzberzerk
  • fouzberzerk
?
anonymous
  • anonymous
yes there is one
fouzberzerk
  • fouzberzerk
Is it A?
anonymous
  • anonymous
go through each one properly
anonymous
  • anonymous
lets start with A
anonymous
  • anonymous
|–5|, 0, 3, –|–4|
anonymous
  • anonymous
what is |-5|
fouzberzerk
  • fouzberzerk
5
anonymous
  • anonymous
so we have order 5,0,3 right?
fouzberzerk
  • fouzberzerk
Yes, it says go least too greatest.
anonymous
  • anonymous
correct. so that is wrong
fouzberzerk
  • fouzberzerk
B. –7, –|–3|, 0, |–4|f
fouzberzerk
  • fouzberzerk
B. –7, –|–3|, 0, |–4|
anonymous
  • anonymous
what is -|-3|
fouzberzerk
  • fouzberzerk
-3
anonymous
  • anonymous
correct what is |-4|
fouzberzerk
  • fouzberzerk
4
anonymous
  • anonymous
so we have order -7,-3,0,4
anonymous
  • anonymous
is that smallest to greatest?
fouzberzerk
  • fouzberzerk
Ah, I see.
fouzberzerk
  • fouzberzerk
Next question
fouzberzerk
  • fouzberzerk
Which lists all the integer solutions of the equation |x| = 4? A. –4 and 4 B. 0 and 4 C. –4 only D. 4 only
anonymous
  • anonymous
thats apply the rule |a|=a and |-a|=a
anonymous
  • anonymous
same concept
anonymous
  • anonymous
what is |4| =? and |-4|=?
fouzberzerk
  • fouzberzerk
So D correct?
anonymous
  • anonymous
why d?
fouzberzerk
  • fouzberzerk
|-4| = 4
fouzberzerk
  • fouzberzerk
Sorry, A?
anonymous
  • anonymous
good!
fouzberzerk
  • fouzberzerk
That is correct?
anonymous
  • anonymous
you used your brain!
anonymous
  • anonymous
yep
fouzberzerk
  • fouzberzerk
Which values satisfy the inequality? |z| ≤ 5 Choose all answers that are correct. A. z = –6 B. z = –5 C. z = –1 D. z = 8
fouzberzerk
  • fouzberzerk
It's a multi-choice.
anonymous
  • anonymous
i figured
anonymous
  • anonymous
all that is saying, is what values of z can take so it can be less than or equal to 5
anonymous
  • anonymous
so is a correct? and explain why it is or isn't
fouzberzerk
  • fouzberzerk
So, A, B, and C correct?
fouzberzerk
  • fouzberzerk
Those are all less then 5.
anonymous
  • anonymous
why is A right
fouzberzerk
  • fouzberzerk
Because -6 is less than 5.
fouzberzerk
  • fouzberzerk
Wait, I see the trickery here.
anonymous
  • anonymous
but you plug it into the |z| so what is z in a
anonymous
  • anonymous
haha good
fouzberzerk
  • fouzberzerk
It would be B and C.
anonymous
  • anonymous
yep!
fouzberzerk
  • fouzberzerk
Alright, last question m8
anonymous
  • anonymous
haha no problem
fouzberzerk
  • fouzberzerk
Sorry, that was the last question. I will fan you and medal you as promised as I got a 100%
anonymous
  • anonymous
haha thanks!
