The local zoo is filling two water tanks for the elephant exhibit. One water tank contains 34 gal of water and is filled at a constant rate of 4 gal/h. The second water tank contains 30 gal of water and is filled at a constant rate of 2 gal/h. Explain. Let x = the number of hours the tanks are filling and let y = the number of gallons in the tank. What are the constraints on the system?

y = 4x , and y = 2x since x is a natural variable to choose for "h"ours ....
the constraints tho ... i dunno what thats actually asking for
A. both x0, y0
B. x0 only
C. y0 only
D. There are no constraints on the system.
Not the answer you are looking for? Search for more explanations.
well, we dont want to go over and waste water id assume so we would have to have a constraint on how long to run the water (xo), which implies a constraint on how much water you can get (yo).
if i were to take a guess, I would say A; but thats only a guess.
Which ordered pair is a solution of the inequality?
y>=4x - 5
im sure your given options with that, so just plug in the values to see which one fits.
A. (3, 4)
B. (2, 1)
C. (3, 0)
D. (1, 1)
i dont really know this kind of stuff
its simple if you can add and multiply .... the notation might be whats wierd tho
an ordered pair is formed from x and y values and are displayed as (x,y)
the number on the left is your x value; the number on the right is your y value.
plug in each ordered pair one at a time into the "equation" and see if the results make sense or not
@RYSSA2K10, it is more appropriate to post only one question per thread.
