The steps shown in the solution process involve multiplying both sides of the inequality \( 43d \geq -20 \) by \( 34 \). The justification for this step is based on the "Multiplication Property of Inequality."
The Multiplication Property of Inequality states that if you multiply or divide both sides of an inequality by a positive number, the direction of the inequality remains the same. Since \( 34 \) is positive, the inequality \( 43d \geq -20 \) remains true when both sides are multiplied by \( 34 \).
So, the correct response is Multiplication Property of Inequality.
