Q. Solve the compound inequality. Give the solution set in both interval and graph forms.−4x≤−8 or −4x≥0Select the correct choice below and, if necessary, fill in the answer box to complete your choice.A. The solution set is □(Type your answer in interval notation.)B. The solution set is ∅.
Divide and Flip Inequality: Divide both sides of the first inequality by −4, remembering to flip the inequality sign because we're dividing by a negative number: −4x≤−8 becomes x≥2.
Solve Second Inequality: For the second inequality, −4x≥0, divide both sides by −4, again flipping the inequality sign, to get x≤0.
Combine Solutions: Now we have two inequalities: x≥2 and x≤0. Since it's an "or" compound inequality, we combine the solutions.
Interval Notation: The solution set in interval notation is (−∞,0]∪[2,∞).
Graph Solution: To graph the solution, shade the region to the left of 0 including 0 and the region to the right of 2 including 2.
