what do you call it when you go from -2(3 - 2x) to -6 + 4x ?

OpenStudy (jamaljunior):

associative property

jigglypuff314 (jigglypuff314):

hmm I thought associative would be like a(b*c) = (a*b)c

OpenStudy (sterling234):

What is -2*(3)

OpenStudy (jamaljunior):

-6

OpenStudy (sterling234):

thats where -6 comes from

OpenStudy (sterling234):

-2*( - 2x)

jigglypuff314 (jigglypuff314):

@Sterling234 Jamal is looking for the reason why - aka distributive property and stuff like that

OpenStudy (sterling234):

oh

OpenStudy (jamaljunior):

i hate this!

jigglypuff314 (jigglypuff314):

@JamalJunior You did amazing in the last question! it's the same ideas here! let's see the format for a distributive property: a(b + c) = a*b + a*c -2(3 - 2x) = -6 + 4x does this format look the same? ;)

OpenStudy (jamaljunior):

yes

OpenStudy (sterling234):

when you see a problem like 2(5x) you distribute aka multiply the first term "2" into the parentheses "(5x) to get 10x

jigglypuff314 (jigglypuff314):

therefore for the second line in the table, the answer would be "Distributive Property" do you see why?

OpenStudy (sterling234):

your basically "simplifying'"

OpenStudy (jamaljunior):

is the next one combine like terms?

jigglypuff314 (jigglypuff314):

so close! but not quite... you are moving the x from one side to the other then subtracting it from the 4x

jigglypuff314 (jigglypuff314):

so "combine like terms" is part of the answer, what do you think the other part is? :)

OpenStudy (jamaljunior):

subtract

OpenStudy (jamaljunior):

is the next 1 division

OpenStudy (sterling234):

which link are we on?

jigglypuff314 (jigglypuff314):

subtracting is adding a negative so the answer they want for the third line is "Addition Property and Combine Like Terms"

OpenStudy (jamaljunior):

thats not an ooption :/

OpenStudy (jamaljunior):

ohh third line

OpenStudy (jamaljunior):

my bad

OpenStudy (jamaljunior):

what about the second line??

OpenStudy (jamaljunior):

is this right? https://gyazo.com/3ab42363e3b066378c5a19787368e72f

OpenStudy (jamaljunior):

i put the fourth 1 as division

jigglypuff314 (jigglypuff314):

Perfect! Well done :)

OpenStudy (jamaljunior):

is the fourth line division?

jigglypuff314 (jigglypuff314):

yup!

OpenStudy (jamaljunior):

what about the last line?

jigglypuff314 (jigglypuff314):

... there's more than 4 lines?

OpenStudy (jamaljunior):

there's a total of 5

OpenStudy (jamaljunior):

look at gyazo

jigglypuff314 (jigglypuff314):

http://prntscr.com/ckv90z

OpenStudy (jamaljunior):

oh my bad!

OpenStudy (jamaljunior):

can you help with the last one please?

jigglypuff314 (jigglypuff314):

sure :)

OpenStudy (jamaljunior):

should i post here or new question

jigglypuff314 (jigglypuff314):

new question please ^_^

OpenStudy (jamaljunior):

1 moment

OpenStudy (jamaljunior):

do you need the drop downs?? https://gyazo.com/4379e86ecd4141b372fa3e081aa2e67c

jigglypuff314 (jigglypuff314):

I don't need them ;) what do you think the first option is? ^_^

OpenStudy (jamaljunior):

distributive

jigglypuff314 (jigglypuff314):

that's right!

jigglypuff314 (jigglypuff314):

you've got this, what do you think the second option is?

OpenStudy (jamaljunior):

addition and combine

jigglypuff314 (jigglypuff314):

well the addition property of equality is when you add a number to both sides right? in this case, we're only combining values on one side

OpenStudy (jamaljunior):

so combine like terms only

jigglypuff314 (jigglypuff314):

yup ^_^

OpenStudy (jamaljunior):

idk the next 1

jigglypuff314 (jigglypuff314):

for the next one, they subtracted 6x from both sides then combined it with the -3x

OpenStudy (jamaljunior):

so subtract and combine?

jigglypuff314 (jigglypuff314):

correct :)

OpenStudy (jamaljunior):

next 1 multiplication and combine?

OpenStudy (jamaljunior):

not and combine

OpenStudy (jamaljunior):

just multiplication

jigglypuff314 (jigglypuff314):

you mean going from here to here? http://prntscr.com/ckvcob

OpenStudy (jamaljunior):

yes

jigglypuff314 (jigglypuff314):

I think they subtracted 19 from both sides then combined 19 with 17

OpenStudy (jamaljunior):

ahhh

OpenStudy (jamaljunior):

whats the last 1

jigglypuff314 (jigglypuff314):

36 divided by 9 equals 4

jigglypuff314 (jigglypuff314):

if there's an option that mentions flipping the sign - that happened too

OpenStudy (jamaljunior):

im confused

jigglypuff314 (jigglypuff314):

I probably need to see the options for this one xD

OpenStudy (jamaljunior):

which one 4 or 5?

jigglypuff314 (jigglypuff314):

the last option

OpenStudy (jamaljunior):

what's the 4th one?
