Answer:
x = 4
Step-by-step explanation:
D.
Because 4 divided by 2 is 2
The total amount of angles in quadrilateral is 360.so:
z=360-(122+79+90)
z=360-291
z=69
Check the picture below.
notice the solid circle at -4 and 3, since it includes those points.
also notice the dashed line, though the lines keeps on going those ways, is not included in the piece-wise, since it's not part fo the domain or constraints.
