Can you show your work so I know how?

OpenStudy (anonymous):

find the vertex of the parabola whose equation is y=x2^=8x=12.

OpenStudy (anonymous):

8x+10=6x -8x -8x 10=-2x -5=x

OpenStudy (anonymous):

Can someone help me here?

OpenStudy (anonymous):

-5=x

OpenStudy (anonymous):

dont know how to do that

I can help you.

\[\large \large 8x+10=6x\] You want to find x. So you want to do reverse PEMDAS. So let's get rid of 10! To get rid of 10, you must subtract it by 10 to both side. So 10 -10 is 0. (Cancel out) 6x -10 is equal to 6x -10. So your equation should look like: \[\large \large 8x = 6x -10\] Now subtract 8x to 6x to get: \[\large \large \ 2x = -10.\] The final step is to divide both side by 2. -10 divided by 2 is -5. Therefore, the answer is -5.

You can do it in the beginning if you want, but it would give you a negative number, and it's harder to work with it. So my method is easier. I hope this help!

OpenStudy (goldphenoix):

Wait, nevermind. You don't have to subtract 10 in the beginning. It gives you extra step.
