Answer:
A. Both \(x\ge0,y\ge 0\)
Step-by-step explanation:
The local zoo is filling two water tanks for the elephant exhibit.
Let us assume that,
x = the number of hours the tanks are filling and
y = the number of gallons in the tank.
Tank one contains 34 gal of water and is filled at a constant rate of 4 gal/h. So the inequality function for this is,
\(y\ge 34+4x\)
Tank two contains 30 gal of water and is filled at a constant rate of 2 gal/h. So the inequality function for this is,
\(y\ge 30+2x\)
As number of hours and number of gallons can not be negative, so
\(x\ge0,y\ge 0\)
will be constraints to the system.
