The question is missing parts. Here is the complete question.
Let M = . Find and such that , where is the identity 2x2 matrix and 0 is the zero matrix of appropriate dimension.
Answer:
Step-by-step explanation: Identity matrix is a sqaure matrix that has 1's along the main diagonal and 0 everywhere else. So, a 2x2 identity matrix is:
Solving equation:
Multiplying a matrix and a scalar results in all the terms of the matrix multiplied by the scalar. You can only add matrices of the same dimensions.
So, the equation is:
And the system of equations is:
There are several methods to solve this system. One of them is to multiply the second equation to -1 and add both equations:
With , substitute in one of the equations and find :

Answer:
A. 24 sales
Step-by-step explanation:
We Know:
$1000 paycheck
$30 for every sale
1720 - 1000 = $720 (Sales cost total)
720 / 30 = 24 (sales)
Answer:x=90° y=58° z=32°
Step-by-step explanation:
x=90
y=180-(90+32) sum of angles in a triangle is 180
y=58
y+90+z=180 they are supplementary
58+90+z=180
148+z=180
z=180-148
z=32
