The numerator is the top number of a fraction and the denominator is the bottom number of a fraction
Answer:
y = -3x -2
Step-by-step explanation:
parallel lines have same slope
line d: slope (m) = -3
y intercept (b) = -2
equation y = mx + b y = -3x -2
Let

denote the amount of salt in the tank at time

. We're given that the tank initially holds

lbs of salt.
The rate at which salt flows in and out of the tank is given by the relation


Find the integrating factor:

Distribute

along both sides of the ODE:




Since

, we get

so that the particular solution for

is

The tank becomes full when the volume of solution in the tank at time

is the same as the total volume of the tank:

at which point the amount of salt in the solution would be
