You only flip the inequality sign when you multiply or divide both sides by a negative number.
================================================
Problem 1

The inequality sign flip happens because we divided both sides by -8.
The graph will have a closed circle at 4 with shading to the left.
Three solutions are x = 0, x = 1, x = 2. You can pick any three numbers you want as long as they are 4 or smaller.
================================================
Problem 2

The graph will have an open circle at 13/3 = 4&1/3 = 4.333 approx. The shading is to the left. No inequality sign flip happens because we divided both sides by a positive number.
Your choice of three solutions is correct. You can pick anything smaller than 4.3333
================================================
Problem 3

The solution set is any value 3 or larger. Three solutions are x = 5, x = 6 and x = 7.
The graph has a closed circle at 3 on the number line. The shading is to the right.

Answer:
hours per day
Step-by-step explanation:
Given,
Distance = 192 miles
Rate = 9.6 miles per hour
Lets find her total time of riding by using Distance Formula ( D = RT ).
D = RT
192 = 9.6T
T = 192/9.6
T = 20 hours
Total time she needs to meet goals is 20 hours.
There are 7 days in a week and she plans to ride same hours each day, so that will be:
20/7 hours per day
