True or false?

Answer 1

It is false, this ordered pair is not solution of inequality.

Explanation:

We have given an inequality:

y < Ix-2I +7

We have to check is (3,8) is the solution of the inequality or not?

So, x = 3 , y = 8

y < Ix-2I +7

(8) < I(3) - 2I +7

8 < I1I + 7

8 < 1+7

8 < 8

8 is not less than 8.

So, it is false, this ordered pair is not solution of inequality.

Answer 2

False

Explanation:

The given inequality is
`y\:<\:|x-2|+7`

We substitute

`x=3,y=8`

This implies that;

`8\:<\:|3-2|+7`

`8\:<\:|1|+7`

`8\:<\:1+7`

`8\:<\:8`

This is false.

8 is not less or greater than itself.
