Answer

(,1)[4,) is the final answer.

Steps

Step 1 :Solve the compound inequality: 8x+3>5 OR 2x412.

Step 2 :First, solve the inequality 8x+3>5. Add -3 to both sides to get 8x>8. Divide both sides by -8 to get x<1. Remember that when you divide or multiply by a negative number, you must flip the inequality sign.

Step 3 :Next, solve the inequality 2x412. Add 4 to both sides to get 2x8. Divide both sides by -2 to get x4. Again, remember to flip the inequality sign.

Step 4 :The solution to the compound inequality is x<1 OR x4. This means that x is less than 1 or x is greater than or equal to 4.

Step 5 :In interval notation, this is written as (,1)[4,).

Step 6 :(,1)[4,) is the final answer.
