Asalt solution having a concentration of cin = 2 pounds per gallon flows at a rate of ˙vin = 10 gallons per minute into a 125-gallon capacity tank, while the well-stirred solution is being pumped out at a rate of ˙vout = 5 gallons per minute. if the tank initially contained 500 pounds of salt dissolved in 50 gallons of water. when the amount of salt in the tank reach minimum?

good job you smart son of a gun you are smarter that einstein. 7

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

slope is 35 and 20 miles is the y-intercept.
