Suppose joey has an unexcused absence for the 15th quiz, and he receives a score of zero. recalculate the mean and the median. what property of measures of center does this illustrate?

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.
