Question
(a)The amount of water in a fish tank is between 7 liters and 14 liters, exclusive. Use a for the amount of water in liters.Inequality: Graph:123456789101112131415
Solution
The inequality for the amount of water in the fish tank would be 7 < a < 14. This means that the amount of water, a, is greater than 7 liters and less than 14 liters.
To graph this inequality on a number line:
- Draw a number line from 1 to 15.
- Mark a circle at 7 and 14 on the number line. These circles represent the numbers but are not included in the solution (because the problem says the amount of water is between 7 and 14 liters, exclusive).
- Draw a line between 7 and 14 to represent all the numbers in between.
- The line between 7 and 14, not including 7 and 14, represents all possible values for a.
