Plzz what is 6/11 as a decimal (show work)

To turn it to a decimal you have to do 6 divided by 11.The decimal is 0.545455

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
