@pinklion23

OpenStudy (pinklion23):

OpenStudy (pinklion23):

|dw:1441826066554:dw|

OpenStudy (trwatkins1):

OpenStudy (pinklion23):

|dw:1441826251026:dw|

OpenStudy (pinklion23):

l-6 + 4I + |-13|

OpenStudy (pinklion23):

so they mean 6+4+13 ta daaaaaaa

OpenStudy (pinklion23):

im sure you can do it from there

OpenStudy (pinklion23):

@trwatkins1

OpenStudy (pinklion23):

you there?

OpenStudy (trwatkins1):

yea im back

OpenStudy (trwatkins1):

@pinklion23

OpenStudy (pinklion23):

im here

OpenStudy (pinklion23):

im waiting for you so what do you think the answer is

OpenStudy (trwatkins1):

i have no clue

OpenStudy (freckles):

replace x with -6 replace y with 4 replace z with -13 so you have |-6+4|+|-13| now |-13|=13 was correct but |-6+4| doesn't equal 6+4 you are suppose to computer the sum inside the absolute value first then take the absolute value

OpenStudy (pinklion23):

you do not know what 6+4+13 im sure you know

OpenStudy (pinklion23):

freckles i got it :D

OpenStudy (freckles):

that is incorrect though

OpenStudy (freckles):

@trwatkins1 do you know what -6+4 is?

OpenStudy (trwatkins1):

??? such confuesed

OpenStudy (trwatkins1):

-10

OpenStudy (freckles):

try again

OpenStudy (freckles):

-6+4 also known as -(6-4)

OpenStudy (trwatkins1):

-2?

OpenStudy (pinklion23):

no the answer is positive

OpenStudy (freckles):

right

OpenStudy (freckles):

so you have |-2|+|-13|

OpenStudy (freckles):

now take the absolute value of each term

OpenStudy (freckles):

since you have absolute value around each term

OpenStudy (freckles):

2+13=?

OpenStudy (trwatkins1):

15

OpenStudy (freckles):

right

OpenStudy (pinklion23):

yeah like freckles said U^U

OpenStudy (trwatkins1):

20 is that my answer?

OpenStudy (freckles):

15 doesn't magically turn into 20

OpenStudy (trwatkins1):

no 15 not 20 wtf i right that

OpenStudy (freckles):

it is just 15

OpenStudy (freckles):
