Question

The initial volume of water in a certain pond is 2,000 m3. Each day 0.5 m3 is drained from the pond.

Answer 1

Answer:

Option A The volume of water in the pond after x days

Step-by-step explanation:

Let

y ------> the volume of water in the pond  

x -----> the number of days

we know that

The linear equation that represent this problem is

$y=2,000-0.5x$

This is the equation of the line in slope intercept form

where

the slope is

$m=0.5\ \frac{m^3}{day}$

the y-intercept is

$b=2,000\ m^3$ ----> initial volume of water in the pond

therefore

The expression represent

The volume of water in the pond after x days
