Answer:
The number of solutions of a system is given by the number of different variables in the system, this number has to be the same as the number of independent equations. The coefficients and the augmented matrix of the system show these values in a matrix form. A system has a unique solution when the rank of both matrixes and the number o variables in the system are the same.
Step-by-step explanation:
For example, the following system has 2 different variables, x and y.
In order to find a unique solution to the system, the number of independent equations and variables in the system must be the same In the previous example, you have 2 independent equations and 2 variables, then the solution of the system is unique.
The rank of a matrix is the dimension of the vector generated by the columns, in other words, the rank is the number of independent columns of the matrix.
According to Rouché-Capelli Theorem, a system of equations is inconsistent if the rank of the augmented matrix is greater than the rank of the coefficient matrix. The inconsistency of the system is because you can't find a combination of the variables that will solve the system.
So the (1+2) could be with the 2 under the fraction or not
PEMDAS
simplify parenthasees first
then mulitplicationthen division
then addition and subtraction
6/2(1+2)
if it is
(6/2)(1+2) then go to AAAAAAAA
if it is 6/(2(1+2)) then go to BBBBBBBBB
AAAAAAAAAA
(6/2)(1+2)
simplify 6/2
2/6=3
also simplify 1+2
1+2=3
(3)(3)=9
BBBBBBBB
6/(2(1+2))
simplify inner parthenasees first
1+2=3
6/(2(3))
multiply with parenthaseess
2(3)=6
6/6=1
theh answer is either 9 or 1 depending on where the parenthasees is
Answer:
Similarity means that two figures are the same shape, but not necessarily the same size, color or orientation, congruent means two figures are the same in every form.
Step-by-step explanation:
In my understanding, The Property of Rigid motion holds two points:
- The relative distance between two points stays the same,
- The relative position of the points stays the same
This includes, translations, reflections, and rotation but not to dilutions since it breaks these rules. The relative distance between points gets smaller after dilution.
For this question you have:
1/2 centimeter = 3/4 foot
so you can say:
1/2*2 centimeter = 3/4 *2 foot
so you will have:
1 centimeter = 3/2 foot or 1.5 foot :))))
i hope this is helpful
have a nice day
The graph that represents 2+3 is the one that mean go add then multiply it to the equation that the number will be
