7230 gallons
Explanation:
The total water pumped out is equal to 210 multiplied by 3 which equals to 630 gallons.
This gives the volume of the tank 3 days ago as 630 + 6600 = 7230 gallons
Answer:
The equation of line in the form of Ax + By = C is: 
Step-by-step explanation:
We need to find the equation of line, with the given slope passes through the given point.
Slope m = -4
Point: (-2,-9)
We need to find slope and y-intercept of the line.
The slope of line is given m = -4
Now, we need to find the y-intercept
Using the point (-2,-9) and slope m = -4, we can find y-intercept
The formula used will be: 
Putting values of: y= -9, x =-2 and m = -4

So, y-intercept b = -17
Now, the equation of required line having slope m = -4 and y-intercept b = -17 is:

Writing equation in required form i.e. of Ax + By = C

So, the equation of line in the form of Ax + By = C is: 
You would write it as -4 1/2
