No, the 2 lines can never ever be both parallel and perpendicular if I'm not mistaken. This is because a set of parallel lines will never touch each other at all. However perpendicular lines are two lines that meet up to get an angle of 90. You cannot have two lines that never touch and touch at the same time.
If the function is:
f (x ) = 5 ( x +2 ) / ( 3 ( x-1 ) ( x - 7) then for: f ( x ) = 0
5 ( x + 2 ) = 0
x + 2 = 0
x = -2
Answer: E ) -2 ( only )
A. you would put in 7 for X and 3 for Y.
3 + 7 = 10
2(10) = 20
A full circle = 360 degrees.
The sum of the shaded portions is : 60 + 55 + 45 = 160.
The probability would be the shaded portion divided by the full circle:
160 / 360 = 0.44
