inverse the matrix(2 0 1,3 2 -5,1 -1 0) by gauss jordan method
Let f be the linear transformation represented by the matrix

M = (0 3)
(1 −1)

(a) State what effect f has on areas, and whether f changes orientation.

(b) Find the matrix that represents the inverse of f.

(c) (i) Use the matrix that you found in part (b) to find the image f(C) of the unit circle C under f, in the form;

ax^2 + bxy + cy^2= d,

where a, b, c and d are integers.

(ii) What is the area enclosed by f(C)?
A buffet sells plates for seniors at $6, adults at $9, and children for free. If 150 plates were purchased for total receipts of $960 and twice as many adult plates were purchased as senior plates, how many of each type of plate were sold? 1)This problem can be solved using a system of equations. Identify the variables to be used in the system. 2)Write one equation to represent the total number of plates sold.3) Write one equation to represent the total receipts.4) Describe how a third equation can be written. What is that equation?5) Use a system of equations to solve the problem.

20. Use an inverse matrix to solve the following system of equations.
x + y – 2z = 0
x – 2y + z = 0
x – y - z = -1
Use an inverse matrix to solve the following system of equations.

Show that (a + b/ 1 +( a+b ) = (a / (1 +a)) + (b/1+b)?
Expert sir Hi,how are you,please help me by giving explination
If A is squre n by n matrix then det(det(A))=det(A))^n .
Show that C(A') = C(A^+) where A^+ is Moore- penrose inverse of matrix A.and A' is transpose of A,and C(A') is column space of A'.
