There are no solutions to 2x-5y=9 but if you are solving it by y=mx+b form than your answer would look like this: y=2/5x-9/5
I hope I can help! :)

Changing the slope from negative to positive
Answer:
Efficiency (Work done per day) for :
( ˘ ³˘)/
A & B together = 1/35th
A alone = 1/60th
Thus, efficiency of B alone = Total - A’s efficiency
Step-by-step explanation:
OR Efficiency of B alone = (1/35) - (1/60) = 6/210 - 3.5/210 = 2.5/210 = 1/84th
Hence, since B completes 1/84th work daily, he would take 84 days to complete the work alone.
The anwser is ten because the number i saw is 14 estimate is ten.
