Solving for Matrices
2 answers:
Answer:
option A
Step-by-step explanation:
Steps to write equations in augmented form
Step 1
Write the coefficients of the x-terms as the numbers down the first column
Step 2
Write the coefficients of the y-terms as the numbers down the second column
Step 3
Write the coefficients of the z-terms as the numbers down the third column
Step 4
Write the constants which are in the end of equation in fourth column
Answer:
a.
Step-by-step explanation:
The given matrix is
9x-4y-5z=9
7x+4y-4z=-1
6x-6y+z=-5
The augmented matrix is the coefficient matrix combined with the constant matrix.
The coefficient matrix is obtained by writing the coefficient of the variables as a matrix.
The constant matrix is obtained by writing the constants as a column matrix.
Combining the two gives the augmented matrix;

When we have two arcs in a circle, one larger and one smaller, one will be called the minor arc and the other the minor arc.
The name of the arc depends on its size, for example, given the following green and yellow arcs, the green, which is smaller, will be the minor arc:
Therefore, the larger arc is always called Major arc, not minor arc.
The statement is False.
Answer: False
