<u><em>The proper answer to this question is "the median is subtracting the greatest number in a data set to the least number in a data set therefore the median would change".</em></u>
Reason:
<u><em>The old median would of been:</em></u>
<u><em>100-60=</em></u> <u><em>(remember in order to solve a median you have to subtract the greatest number to the least number)</em></u>
<u><em>Which would equal 40 which would of been the median.</em></u>
<u><em>Since you added the number 0 in the data set you have to subtract:</em></u> <u><em>100-0=</em></u> <u><em>Which would equal 100.</em></u> <u><em>Meaning 100 would be the new median. </em></u> <u><em>Which means when you add the zero is changes (and greatly increases) the median of this data set.</em></u>
<em>Therefore the answer is that the median would change.</em>
Solve as a simultaneous equation maybe? f(x) + g(x) = 2x or x/(x-6) + y =2x and then solve so it becomes 2x^2 + 5x =y then factorise into brackets or use quadratic formula
