5. Inequalities Involving Absolute Value
Sign In
Create an or
compound inequality because the absolute value is greater than the given value.
Solution Set: { p | p<- 4or p>- 23}
Graph:
Let's isolate p in both of these cases before graphing the solution set.
LHS+7
Divide by - 3 and flip inequality sign
Put minus sign in front of fraction
The solution to this type of compound inequality is the combination of the solution sets. First Solution Set:& p< - 4 Second Solution Set:& p>- 23 Combined Solution Set:& p< - 4 or p>- 23
The graph of this inequality includes all values less than - 4 or greater than - 23. We show this by keeping the endpoints open.
