2x-3(x+4)=-5 Simplify.

OpenStudy (solomonzelman):

x=-7

OpenStudy (solomonzelman):

this is not simplifying though, it is solving.

OpenStudy (anonymous):

Can you explain your answer. I got 17. And Yes, it is solving.

OpenStudy (solomonzelman):

2x-3(x+4)=-5 2x-3x-12=-5 (-3 times +4= -12) -x=7....

OpenStudy (solomonzelman):

Get it?

OpenStudy (anonymous):

write a two column proof Given 7y=8y-14 ; y=6 Prove x=7

OpenStudy (solomonzelman):

Geometry?

OpenStudy (anonymous):

yes

OpenStudy (solomonzelman):

where is the x?

OpenStudy (anonymous):

sorry its 8x not 8y

OpenStudy (solomonzelman):

7y=8x-14

OpenStudy (anonymous):

yes

OpenStudy (solomonzelman):

Statement Reason 7y=8x-14 Given y=6 Given 7(6)=8x-14 Substitution 42=8x-14 Multiplication 42-8x=-14 Subtraction -8x=-14-42 Addition -8x=-56 Subtraction x=7 Division

OpenStudy (solomonzelman):

-8x=-14-42 Addition not addition, Subtraction

OpenStudy (solomonzelman):

OK?

OpenStudy (anonymous):

thank you very much would you have time for one more BD bisects <ABC, m<ABD=8x m<ABC=2x+22 find m<DBC

OpenStudy (solomonzelman):

what shape, rectangle? I have to go, studying "Torah" (Jewish version of Bible). Sorry!

OpenStudy (anonymous):

ok thank you fro your help

OpenStudy (solomonzelman):

derivative of f(x)=(2e^x+2sin(x))(-2x+cos(x))

OpenStudy (anonymous):

Simplify the given expression to rational exponent form, justify each step by identifying the properties of rational exponents used. All work must be shown

OpenStudy (solomonzelman):

@qwerter, I never learned about these type of derivatives, but I think this might help http://www.derivative-calculator.net/

OpenStudy (anonymous):

Thanks for the effort anyway!
