How matrices used in engineering?
If you have a system, which can be expressed as a set of linear equations, then you can utilize matrices to help solve it. One example is an electrical circuit which uses linear devices (example are constant voltage sources and resistive loads). To find the current through each device, a set of linear equations is derived.
To solve a system of inequalities graphically you just need to graph each inequality and see which points are in the overlap of the graphs?
True
What is the raven standard progressive matrices?
Raven Standard Progressive Matrices: These were the original form of the matrices, first published in 1938. The booklet comprises five sets (A to E) of 12 items each (e.g., A1 through A12), with items within a set becoming increasingly difficult, requiring ever greater cognitive capacity to encode and analyze information. All items are presented in black ink on a white background
Whats the difference between a linear equation and a system of linear equations?
Quite simply, the latter is a group of the former.A system of linear equations is several linear equations taken together, each using the same group of unknowns. Usually, such a system provides one linear equation for each unknown (x, y, z, et al) that must be found (more complex systems can exist, though). You can use and manipulate these linear equations as you would a single linear equation to help solve for the unknowns. One way is to reduce all but one of the unknowns so that each can be expressed in terms of the remaining unknown and then solve for the remaining unknown which would in turn give you the others.
Is the set of all 2x2 invertible matrices a subspace of all 2x2 matrices?
I assume since you're asking if 2x2 invertible matrices are a "subspace" that you are considering the set of all 2x2 matrices as a vector space (which it certainly is). In order for the set of 2x2 invertible matrices to be a subspace of the set of all 2x2 matrices, it must be closed under addition and scalar multiplication. A 2x2 matrix is invertible if and only if its determinant is nonzero. When multiplied by a scalar (let's call it c), the determinant of a 2x2 matrix will be multiplied by c^2 since the determinant is linear in each row (two rows -> two factors of c). If the determinant was nonzero to begin with c^2 times the determinant will be nonzero, so an invertible matrix multiplied by a scalar will remain invertible. Therefore the set of all 2x2 invertible matrices is closed under scalar multiplication. However, this set is not closed under addition. Consider the matrices {[1 0], [0 1]} and {[-1 0], [0 -1]}. Both are invertible (in this case, they are both their own inverses). However, their sum is {[0 0], [0 0]}, which is not invertible because its determinant is 0. In conclusion, the set of invertible 2x2 matrices is not a subspace of the set of all 2x2 matrices because it is not closed under addition.

How do you solve a problem using scientific notation?
Multiplying each factor by powers of ten
How do you do matrix mathhow to solve matrix related math?
How to solve will depend on what the specific question is. There are entire books dedicated to learning matrices (and related topics); the title of such books often includes something like "linear algebra" - therefore, the topic can't be appropriately summarized here, in one or two paragraphs. You can find an introduction in the corresponding Wikipedia article.Specifically, to add two matrices (which must have the same size), you add the corresponding elements. To multiply a scalar by a matrix, you multiply the scalar by each element. Multiplying one matrix by another is an important operation, but since it's a bit more complicated, I think you should better check the Wikipedia article for examples.
Can two matrices be equal?
Only if each element of one has the same value as the corresponding element in the other.
How many different ways can you arrange the word solve using each letter only once?
120 different ways.
How is algebra used in enginerring?
one example is to solve for the forces in each part of a system/structure if it has an external force acting on it.
Use Elements in the periodic table yo solve each pun?
Sure, feel free to provide a pun that you would like me to solve using elements from the periodic table.
How do you solve queefing?
Do about a half hour of crunches each day. It gets rid of any stored up gas or air in your system.
To solve a system of inequalities graphically you just need to graph each inequality and see which points are in the overlap of the graphs?
