It would be -25% !!!!!!!!
I think it is 90
Hope this help you?!
This one.
The doubly-shaded area is the solution set. The dashed line is not included.
The triangle inequality applies.
In order for ACD to be a triangle, the length of AC must lie between CD-DA=0 and CD+DA=8.
In order for ABD to be a triangle, the length of AC must lie between BC-AB=3 and BC+AB=9.
The values common to both these restrictions are numbers between 3 and 8. Assuming we don't want the diagonal to be coincident with any sides, its integer length will be one of ...
{4, 5, 6, 7}
Y = 2x - 8 is perpendicular to 6x+12y=24 and passes through (4,0)
