Match each set of points with the slope of the line formed by the ordered pairs.

Maksim231197 [3]

Answer:

(0,7) and (2,4) go to slope =-3/2

(1,-3) and (-1,-3) go to zero slope

(0,0) and (2,1) go to slope =1/2

(0,-1) and (2,-5) go to slope =-2

and (-1,3) and (-1,-3) go to no slope

A square matrix A is said to be idempotent iff A2 = A. (i) Show that if A is idempotent, then so is I − A. (ii) Show that if A i

muminat

Answer:

Step-by-step explanation:

Given that A is a square matrix and A is idempotent

$A^2 = A$

Consider I-A

i) $(I-A)^2 = (I-A).(I-A)\\= I^2 -2A.I+A^2\\= I-2A+A\\=I-A$

It follows that I-A is also idempotent

ii) Consider the matrix 2A-I

$(2A-I).(2A-I)=\\4A^2-4AI+I^2\\= 4A-4A+I\\=I$

So it follows that 2A-I matrix is its own inverse.
