Question

12b - 15 > 21 graphed

Answer 1

Given inequality:

12b - 15 > 21

To find:

The graph for the inequality.

Solution:

`12b - 15 > 21`

Add 15 on both sides.

`12b - 15 +15> 21+15`

`12b> 36`

Divide by 12 on both sides.

`$(12b)/(12) >(36)/(12)`

`b>3`

• Open circle means the value of 3 is not included.
• Closed circle means the value of 3 included.

Here b is strictly less than 3. so it is open circle.

The image of the graph is attached below.

The solution of the inequality is b > 3.
