Find how much work they get done in 1 hour jackie takes 5 hours to do 1 room, so in 1 hour, she does 1/5 room voilet take 6 hours to do 1 room so in 1 hour, she does 1/6 room
together, they do 1/5+1/6 room in 1 hour make common denom 1/5+1/6=6/30+5/30=11/30 in 1 hour 11/30 times time=1 room times both sides by 30/11 time=30/11 hour time=2 and 8/11 hour that is about 2 hours and 44 mins
Y - y1 = m(x - x1) slope(m) = -56 (8,-4)...x1 = 8 and y1 = -4 now we sub...pay close attention to ur signs y - (-4) = -56(x - 8)....not finished yet y + 4 = -56(x - 8) <===
