Question

please answer the above question​

Answer 1

Answer:

Let M=[a b]

[a b] [1 1]. =[1. 2]

[1 2]

a+b=1

a+2b=2. It implies a=0,b=1

M =[0 1]

Answer 2

Answer:

the order of matrix M=1×2

Step-by-step explanation:

let M=

[a b]

[a b]×matrix 1 1

1 2

= matrix a+b a+2b=[1 2]

=>a+2b=2->1

a+b=1->2

1-2

b=1

a+b=1

=>a=1-1=0

M=[0 1]
