A tank is completely filled with water. A pump is used to drain the tank. The amount of water remaining in the tank is given by the equation y = 600 – 25.x, where x is the number of minutes since the pump started and y is the volume, in gallons, of water remaining in the tank. In the equation, what are the meanings of the numbers 25 and 600? A) The number 25 is the number of minutes it will take to drain the tank, which holds 600 gallons of water. B) The number 2 is e rate of increase, in gallons per minute, of the flow from the tank, which holds 600 gallons of water. C) The number 25 is the rate of increase, in gallons per minute, in the volume of water in the tank, which started at 600 gallons. D) The number 25 is the rate of decrease, in gallons per minute, in the volume of water in the tank, which started at 600gallons.

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Question

A tank is completely filled with water. A pump is used to drain the tank. The amount of water remaining in the
tank is given by the equation y = 600 – 25x, where x is the number of minutes since the pump started and y is
the volume, in gallons, of water remaining in the tank. In the equation, what are the meanings of the numbers 25
and 600?
A) The number 25 is the number of minutes it will take to drain the tank, which holds 600 gallons of water.
B) The number 2 is e rate of increase, in gallons per minute, of the flow from the tank, which holds 600 gallons
of water.
C) The number 25 is the rate of increase, in gallons per minute, in the volume of water in the tank, which started
at 600 gallons.
D) The number 25 is the rate of decrease, in gallons per minute, in the volume of water in the tank, which started
at 600gallons.
