PROBLEM
Solve and graph the inequality . Plot endpoints, change one to open, and delete the middle section.
STEP 1
Assumptions1. The inequality to solve is
. We need to find the value of that satisfies the inequality3. The inequality is linear, meaning it involves a variable to the first power4. The solution will be a range of values, not a single value
STEP 2
First, we need to simplify the left side of the inequality. We can do this by distributing the5 to both terms inside the parentheses.
So, the inequality becomes
STEP 3
Next, we need to isolate the variable on one side of the inequality. We can do this by adding30 to both sides of the inequality.
This simplifies to
STEP 4
Finally, to solve for , we need to divide both sides of the inequality by.
This simplifies to
SOLUTION
Now that we have the solution to the inequality, we can graph it. Since is greater than or equal to8, we will draw a closed circle at8 (indicating that8 is included in the solution) and draw a line extending to the right (indicating all numbers greater than8).
So, the solution to the inequality is .
