Answer:
2x + 120 = 180 (being co interior angle)
or, 2x = 180 - 120
or, 2x = 60
or, x = 60/2
or, x = 30
therefore 2x = 2* x = 2* 30= 60

Simpler Answer:
128 / 8 = 16
5.12 / 16 = 0.32
Well without seeing the tables it is hard to answer. However, I will offer some help. f(x) is actually y. A function of x=y. So, now you have y=2x-1. Plug the x and y values in from the tables and make sure the equations are true with the given values (equal on both sides). For example, (2,3).. 3=2(2)-1...... 3=3. Hope this helps.
