This is my problem:
I need x or y for the triangle area that forms between the vertical axis(y) and the function y=100+2x where the area is equal to 2500.
so I used for condition to the linear function:
knowing that the triangle area in this case should be like:
x-100*y/2=2500 x-100*y=5000 y=5100/x
5100/x=100+2x 5100=100+2x*x 5000=2x^2 sqrt(2500)=x 50=x
the weird thing is that works for any area, and gives me the correct result for what I'm looking for, wich is x=50 and y=f(50)=200, if the area is calculated as is shown in the condition: 200-100*50/2=2500 !
x=-5 (5+sqrt(127)) and
how can I get the same results on wolframalhpa ?
thank you ! (:
