Hello,
To exist x≠0
if x>0 then
x+2/x>=3==>x²+2>=3x
==>x²-3x+2>=0
==>(x-2)(x-1)>=0 positive out of the roots
==> (x<=1 or x>=2) and x>0
==>(0<x<=1) or (x>=2)
else
x<0
x+2/x>=3==>x²+2<=3x
==>x²-3x+2<=0 negative betheen the roots
==>(1<=x<=2) and x<0 : no solution
end if

Answer: median:3
Mean:4
Mode:2
Step-by-step explanation:
The angle that is next to 9x should be 180 - 9x because it is a straight angle.
Since there are 180 degrees in an angle we can add up the values to 180 and solve for x.
180- 9x + 5x + 9 + x = 180
-3x = -9
x = 3
Hope this helped!
