Answer:
C = 0.75(n/2)
Step-by-step explanation:
For each pair of signs, $0.75 is needed for the posterboard.
C = 0.75(n/2)
This can be simplified to ...
C = 0.375n . . . . for n an even number
__
If posterboard only comes in the size given, then the more technically correct answer is ...
C = 0.75·ceiling(n/2)
Two lines are guaranteed to be coplanar if they: Lie in the same plane. Lie on the same line (are collinear) and Lie in the same plane. ... Collinear points are two or more points that lie on the same ____.
Solution is (2,3)
X intercept of boundary line is (-3/2,0)
The answer for 5+(-3) is 2
