i got it straight from my homework i just looked again it is the same
Is that 8 times 2?
i think it is 7x minus 15
i think it is 8 times 2 plus 7x minus 15 = negative 7.
Multiply out 8 * 2 and add it to -15
then subtraact that new value to the -7 and divide by 7 and that should give you your x.
wait so 8*2 is 16 then adding it to -15 would be 1 right then you subtract that from -7 would be 8 and dividing it would 1.14 right? it says i have to have two decimals though so what do i do after that?
it would be -8 not 8. so it should give you -1.14 if you did your calculuations correctly. 1.14 is two decimal places. you have the tenths and the hundredths places.
no like 1.14 as one answer than there should be another answer for it
I think this is supposed to be a quadratic and you're going to want to use the quadratic formula...
first write it in the form ax^2 +bx +c =0 then plug the values of a b and c into the quad. formula
I don't quite understand this then. So that is not a multiplication like you said it's 8x?
it is from the lessons linear and quadratic functions
Oh so then that is not 8 times 2 , it's 8x^2
im so confused guys
Forgetting that little carrot is a huge thing.
it didnt have the carrot thingy
re-write it in the form ax^2 +bx +c =0 plug the values of a b and c into the quad. formula
where do i find the a b c thing
a=8 b =7 c=...?
or are you talking about the quadratic formula?
i have no clue honestly i am so confused right now
@Algebraic! : i'm not sure it's a quadratic equation sine he just said there was nothing squared. so the qudratic formula would render usless he made a mistake in copying the problem.
it's in your book or everywhere on the internet
im a girl first and second the problem is right in front of me it is right. and it is on my homework online
i got it guys thanks
Sorry about that!
no its fine thank you for trying
"im a girl first " so?
he kept calling me a dude
