You can start by rewriting the equation so that the right side equals zero. Add

and

to both sides.

You can now use the quadratic equation (below), where

and

, to find solutions. Plug in these values for

and

into the equation and simplify.




The final answer is the combination of both solutions.

Or approximately...
Answer:
40 hours will it take for the pool to fill.
Step-by-step explanation:
A pump can fill a swimming pool in 8 hours.
Work done by pump to fill in 1 hour is 
The pool also has a drain that can empty the pool in 10 hours.
Work done by pump to drain in 1 hour is 
If someone turns on the pump to fill the pool, but forgets to shut the drain.
Work done by both pipe in 1 hour is




Both pipe filled
part of pool in hours = 1
Both pipe filled complete pool in hours = 
Therefore, 40 hours will it take for the pool to fill.
Answer:
Ok please solve with work
Step-by-step explanation:
Answer:
B) y=0
Step-by-step explanation:
The exponential function shown has a horizontal asymptote at the line y=0, which means that y will approach 0 as the value of x decreases. Therefore, B is correct.
60*(1-x)=36
60-60x=36
-60x=36-60
-60x=-24
x=24/60
x=4/10
x=2/5
x=0.4
36 is 40% less than 60
