Yes, I have an idea.
Take the (-4) and put it into the F(x) in place of the 'x'.
Try it and let us know if it works.
The answer would be B. (0, 5)
Remember, x always comes first in ordered pairs, and y follows afterward.
A.
earnings=bonus+pay
pay=pay per hour times number of hours
h=number of hours
9.5=pay per hour
pay=9.5h
bonus=60
earnings=9.5h+60
at least 460
greater than or equal to 460
9.5h+60<span>></span>460
B. solve for h
9.5h+60<u>></u>460
subtract 60
9.5h<u>></u>400
divide oth sides by 9.5
h<u>></u>42.1
at least 42.1 hour (about 42 hours and 6 minutes, if the job is rounding, then say 43 hours)
A. 9.5h+60<u>></u>460
B. 42.1 hours
