OpenStudy (phebe):

What is the value of -2x^3++x-7 When x=-3

OpenStudy (phebe):

ok so its -28

OpenStudy (phebe):

wait it cant be -28 none of my answer choices say that

OpenStudy (nfcfox):

No I screwed up it's cubed not squared.

OpenStudy (phebe):

yeas it cubed

OpenStudy (nfcfox):

-2(-3)^3 +(-3)-7) Ok so we get -2(-27) -3 -7. We simplify and get 54-10 which is 44. The answer is 44.

OpenStudy (phebe):

noo thas wrong too cuz none of my answer choices say that LOL

OpenStudy (phebe):

@mitchal think u can help me thoe

OpenStudy (anonymous):

hard to find the question lol

OpenStudy (anonymous):

-2(-3)^3 +(-3)-7

OpenStudy (phebe):

OpenStudy (phebe):

yea thas the Q

OpenStudy (anonymous):

okay now we do the order of operation

OpenStudy (anonymous):

which is PEMDAS

OpenStudy (phebe):

ok

OpenStudy (anonymous):

exponets go first obivlosy

OpenStudy (anonymous):

but when the paratheis inside the -3 it means it go like this -3 times -3 times -3 instead of -3 times 3 times 3

OpenStudy (anonymous):

so it be -27

OpenStudy (nfcfox):

@mitchal dude you wasting your time answering questions that were already answered lol

OpenStudy (nfcfox):

No type out the question without inputting the -3. I can arleady fking tell it's 44 based off what u just said.

OpenStudy (phebe):

What is the value of -2x^3++x-7 When x=-3

OpenStudy (nfcfox):

Why are there two plus signs?

OpenStudy (nfcfox):

Maybe take a screen shot of the problem?

OpenStudy (phebe):

u sure ohjhh my lolt thanx can u help with number 1 too

OpenStudy (nfcfox):

OpenStudy (nfcfox):

Ok this is simply asking us to form a problem. Wouldn't you agree that the $30 is a constant and doesn't need to bemultiplied by a t? The money that depends on t (amount of months) is $18 per month meaning the equation will be c: t*18 +30

OpenStudy (phebe):

yes

OpenStudy (phebe):
