Such an equation would represent an ill-posed problem for all positive time (i.e. the solution is not defined). The irreversibility of diffusive processes is closely related to the second law of thermodynamics.

Negative 45y equals negative 90 solve for y?
y = 2 (Divide each side of the equation by -45)
How can you recognize the slope intercept form of an equation?
If you solve for y with no coefficient, you should have an equation in the form of y = mx + b, where m is the slope and b is the y intercept.
What does x equal in the equation x plus 5 equals negative 13?
Set up the equation and solve: x + 5 = -13 (next subtract 5 from each side of the equation to solve for x) x = -18
Can you solve for b in the equation 12 equals negative 4 over 2 plus b?
b = 14
How do you find the coefficient of x in an equation?
For example ?x+20=50x then solve: 50x-20=30x 30x/x=30 then the answer is 30 you just have to dived the answer by x
How do you solve a diffusion equation with a negative diffusion coefficient numerically It is unstable at all. Solving it with finite difference is best?
Diffusion does not require the cell to expend ATP. Therefore, diffusion is considered a type of passive transport.
The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is?
The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.
What is the quadratic formula cannot be used to solve an equation if the coefficient of the equation x square term is?
The quadratic formula cannot be used to solve an equation if the coefficient of the equation x square term is what?
To solve an equation of the form ax b you need to divide by the what?
I believe its coefficient.
How is the multiplicative inverse used to solve an equation that has a rational coefficient?
When you multiply both sides of the equation with the multiplicative inverse of the coefficient then the coefficient becomes one. 1/2*x =5 2*1/2*x=2*5 1x=10 x=10
Why can't an equal 0 in a quadratic equation?
a is the coefficient of the x2 term. If is a = 0, then it is no longer a quadratic - it is just a linear equation, and the quadratic formula will not work to solve it.
What do you do when you have a negative variable?
When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.
How do you solve compound inequalities?
For example, let's start off with: 9x + 3 > 3x + 2First, get rid of the smallest 6x + 3 > 2variable, 3x, by subtracting3x from 9x.Then, subtract 3 from both 6x > -1sides to isolate thevariable.Now divide each side by x > -1/66 to get x alone to solvethe inequality.Summary: Subtract one coefficient from another coefficient to get one coefficient on one side of the equation. Subtract one constant on one side of the equation from the other so that the coefficient is completely alone on its side of the equation. Finally, if their is a constant attached to the variable, which the pair is called a coefficient, divide whatever the constant of the variable is on both sides of the equation to get the variable alone to solve the equation.
