Since is addition you do the opposite and subtract 12 from 12 and -5 then 12 cancels out and -5-12=-17
right angle because its always perpendicular to the floor
Malia : y = 8.1x.....this tells me she makes 8.10 per hr worked
Bill : if he earned 144.90 for working 18 hrs.....144.90/18 = 8.05 per hr worked.
so Malia makes 5 cents more per hr worked.
Is that the answer ur looking for ?
The question doesn’t make sense.
