QuestionSolve the inequality and express the solution in interval notation.
Studdy Solution
STEP 1
Assumptions1. We are given a linear inequality . We need to solve for and express the solution in interval notation3. We also need to graph the solution set
STEP 2
First, we need to get rid of the fractions to simplify the inequality. We can do this by finding a common multiple of the denominators4 and, which is12. Multiply each term by12.
STEP 3
implify the inequality.
STEP 4
Expand the brackets.
STEP 5
implify the right side of the inequality.
STEP 6
Subtract from both sides of the inequality to isolate terms on one side.
STEP 7
implify the inequality.
STEP 8
Divide both sides of the inequality by8 to solve for .
STEP 9
implify the fraction on the right side.
This is the solution in inequality form.
STEP 10
To express the solution in interval notation, we write it as .
STEP 11
To graph the solution set, draw a number line and mark on it. Since the inequality is greater than or equal to, we use a closed circle at to include this value in the solution set. Draw an arrow to the right of to indicate all numbers greater than .
The solution to the inequality is , which is in interval notation. The graph of the solution set includes and all numbers greater than .
