How to find inverse of a matrix ?
Only square matrices with an equal number of rows and columns, such as 2 *2, 3* 3, etc., allow us to find the inverse of the matrix. The adjoint of the provided matrix is divided by the determinant of the given matrix to produce the inverse matrix, to put it simply.
|A|=-5(4-3)+4(4-3)-5(4-4)
|A|=-5+4
|A|=-1

Answer:
2400 pages
Step-by-step explanation:
Printer 1 : 50+ 1.50/30 x where x is the number of pages
Printer 2 : 10 + 2/30 x where x is the number of pages
Set them equal
50+ 1.50/30 x = 10 + 2/30 x
50 + 1/20x = 10 +1/15 x
Subtract 1/20x from each side
50 + 1/20x -1/20x= 10 +1/15 x-1/20x
50 = 10 +1/15x - 1/20x
Subtract 10 from each side
40 = 1/15x - 1/20x
Get a common denominator
40 = 4/60x - 3/60x
40 =1/60x
Multiply by 60
40 *60 = 1/60x *60
2400 =x

Step-by-step explanation:
The <em>correct answer</em> is:
Discrete graph.
Explanation:
A discrete graph is a graph of disconnected points.
Since they are disconnected, this means the graph only has values at the points drawn, not between.
The opposite of a discrete graph is a continuous graph; it is a graph of connected points. Since the points are connected, the graph has values between all of the points. This is similar to what we learned in geometry about a line; a line has an infinite number of points. This is true of the connections between points in a continuous graph.
Since a discrete graph is the opposite of a continuous graph, this means it does <em>not</em> have an infinite number of points; a discrete graph has a <em>finite</em> number of points.
