Linear Algebra
Linear algebra is the detailed study of vector spaces. With applications in such disparate fields as sociology, economics, computer programming, chemistry, and physics, including its essential role in mathematically describing quantum mechanics and the theory of relativity, linear algebra has become one of the most essential mathematical disciplines for the modern world. Please direct all questions regarding matrices, determinants, eigenvalues, eigenvectors, and linear transformations into this category.

What happens to the cross products when the terms of a proportion are cross multiplied?
The cross product is created.
What is the equation of the line passing through 5 4 and the x intercept is 3?
The equation is y = 5x - 15 or y = 5*(x - 3)
How do you solve compound interest formula for n?
It depends on which compound interest formula you mean. Refer to the Wikipedia Article on "Compound Interest" for the correct terminology.
How do you solve systems of equations using linear combination?
You select the linear combination of the equations in such a way that at each stage you eliminate one variable.

Escalation matrices are used as a hierarchy system in case of major issues. They contain multiple user contacts that can be contacted in a certain order should something go wrong with parameters, such as time zone, schedule, partner, and customer.

What is the purpose of locating the circumcenter?
It identifies the point which is equidistant from the three vertices of the triangle. If, for example, you wanted to locate a phone mast to supply three remote locations, a good starting point would be to find somewhere which is at or very close to the circumcentre. Of course, local geography (hills, for example) would have to be taken into account.
No answer is possible. As soon as you have one valid line, all points that are not on that line cannot be part of the solution set. Therefore the solution set cannot be all real numbers.

When solving a system of linear inequalities what does the region that is never shaded represent?
It represents the solution set.
What is a two step equation that equals 28?
.5x+3=17 subtract 3 from each side and multiply both sides by 2 and you have x=28
D.) 0.009l = 0.011g
l = g+800
EFE Matrix is a tool used in the business world, designed to assess current business conditions. It stands for External Factor Evaluation Matrix. It identifies critical success factors for a company and assigns a weight to each factor.
How do you solve a linear equation that doesn't have a Y in it?
What's the equation???
OR
If there is no Y in the equation it is a vertical line at that place. For example x = 1 indicates a vertical line drawn straight up and down parallel to the y-axis through the points (1, 00, (1,1), (1,2), (1,3), etc.
The first mathematicians are unknown to us; that was so long ago that writing didn't even exist then. Not true the first PEOPLE to create math were the african american women not the romans they created roman numerals the african american women created math as we know it today
Can the dot product of two nonzero vectors be equal to zero?
Yes, if the dot product of two nonzero vectors v1 and v2 is nonzero, then this tells us that v1 is PERPENDICULAR to v2.
:)
This is a simple thing to check. The inequality will either be y< or y> (less than y or greater than y). You know the area above the x-axis, where y=0, is where y is greater and the area below is where y is less. So the area above your graphed line is where y is greater and the area below your line is where y is less. This is easiest to check in a linear portion of your graph, i.e. the minimum or maximum point on a parabola.
They are "like terms".
