Question

- IF A ---------->
3x3, A is skew - symmetric, then |A|
​

Answer 1

Answer:

it will be equal to zero |A|=0

Answer 2

Given inequality 2x+3y>6

3y>6−2x

y>6−2x

Now consider y=

36−2x

and plot the graph [Ref. image 1]

X 0 3

Y 2 0

we used dashed as

y>

6−2x

as there in no equal to sign

∵ y is greater than

3

6−2x

we will shade the upper part [Ref. image 2]

Thus the graph of 2x+3y>6 is drawn

Among the option only {B} true

option [B]: half-plane the neither contains origin nor the points of the the line 2x+3y=6
