Answer 1

Using elementary transformations, find the inverse of the matrix ( 1 3 −2 3 0 −1 2 1 0 )

Answer 2

Step-by-step explanation:

Given: −3(x−7)≥15−7x>

3

x+1

−3x+21≥15−7x>

3

x+1

⇒−3x+21≥15−7x and 155−7x>

3

x+1

⇒4x≥−6 and 45−21x>x+1

⇒x≥−

2

3

and 44>22x

⇒x≥

2

−3

and 2>x

∴ Solution set ={x:x∈R,
