How would you know that your equation has no solutions without actually solving it?
It really depends on the type of equation. Sometimes you can know, from experience with similar equations. But in many cases, you have to actually do the work of trying to solve the equation.
How do you apply linear algebra to economics?
The application of linear algebra to economics lies primarily in its use of matrices. A matrix in economics is used as a means to solve a large number of linear equations at once, where the variables are economic indicators and factors. As a whole, then, a matrix represents a transformation from one state to another state, and one can view the economy as a succession of such states. The methods can be extended to linear combinations of non-linear equations, where the entries might be operators rather than numbers. Given the huge number of factors involved, linear algebra has various methods for reducing the complexity of the problem. It also investigates properties of matrices such that one need not always waste time trying to find the precise solutions in order to determine some property of the system. Simulations of systems often use matrices.
Why is it better to solve quadratic equations in the complex number system rather than in the real number system?
It is not always better.Although quadratic equations always have solutions in the complex system, complex solutions might not always make any sense. In such circumstances, sticking to the real number system makes more sense that trying to evaluate an impossible solution in the complex field.
What symbol will you find in every linear equation?
The equals sign ( = ). In fact it defines any equation, linear or not, since an equation is a statement that a particular value or term is equal to, so the result of solving, a second set of terms and operators. Any other symbols would be particular to the equation you have derived or are trying to solve.
What is its linear equation and how would you write in standard form if x plus y to the second power equals 25?
You were going along pretty good until you hit the words "to the second power". Right there, you no longer have a 'linear' equation. The question looks like you're trying to say one of the following two equations: Either x + y2 = 25 or (x + y)2 = 25. Neither is a linear equation. Each is the equation of a parabola.
How many linear feet is twenty thousand square feet?
Linear means length, square means area. You are trying to compare the incomparable.
What is more 3780 linear feet or 5000 square feet?
You are trying to compare length with area.
How do you solve the contraption with the equations on riddle transfer?
Honey, solving that contraption is as easy as stealing candy from a baby. Just plug in the numbers and do the math, it's not rocket science. If you're still struggling, maybe it's time to brush up on your basic arithmetic skills. Good luck, you're gonna need it.
What is the first step in solving this equation by completing the square?
The first step would be to find the equation that you are trying to solve!
How is Mexico solving their job issue?
They are trying to control negative challenges such as poverty and lack of education. See related questions.
When trying to solve a problem what does a scientist do with things learned from other scientists?
A scientist uses the information as a beginning for solving a problem.
What is a simile for difficult?
this is as difficult as trying to break iron with you bare hands. this is as difficult as trying to pass a test without studying. this is as difficult as trying to sing a song without the lyrics.
