Best ResponseYou've already chosen the best response.0i think it is 8 times 2 plus 7x minus 15 = negative 7.

Best ResponseYou've already chosen the best response.0then subtraact that new value to the 7 and divide by 7 and that should give you your x.

Best ResponseYou've already chosen the best response.0wait 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?

Best ResponseYou've already chosen the best response.0it 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.

Best ResponseYou've already chosen the best response.0no like 1.14 as one answer than there should be another answer for it

Best ResponseYou've already chosen the best response.0first write it in the form ax^2 +bx +c =0 then plug the values of a b and c into the quad. formula

Best ResponseYou've already chosen the best response.0I don't quite understand this then. So that is not a multiplication like you said it's 8x?

Best ResponseYou've already chosen the best response.0@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.
