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?

sanchez9457Best ResponseYou've already chosen the best response.0
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

@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.
