If A=[1 0 -1 7] find K such that A^2-8A-ki-KI=0

K = -7

Step-by-step explanation:

If A=[1 0 -1 7] find K such that A^2-8A-ki-KI=0

Given the 2×2 matrices

A =

We are to find K if  =0

A² =  

A² =

8A = 8

8A =

Since

Substitute the resulting matrices into the expression above:

A^2-8A-KI =   - - =

From the expression, we have the equations;

1 - 8 - k = 0

-7 - k = 0

-7 = k

k = -7

Hence the value of K is -7

0 is its x and y coordinate

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.
