F(x) = 20x+300
you sub in the x values (120 hours and 100 hours) for each equation
the only one they both work for is the last one
f(x) = 20x + 300
f(100) = (20 * 100) + 300 = 2000 + 300 = 2300
f(120) = (20 * 120) + 300 = 2400 + 300 = 2700
C.
An angle bisector splits angles into halves thus resulting in PNQ. The total angle is however twice the PNQ so 4x + 2.
Hope this helps.
