The property of inequality that justifies the steps shown in the solution process is the Multiplication Property of Inequality.
This property states that if you multiply both sides of an inequality by a positive number, the direction of the inequality remains the same. In your case, both sides of the inequality \(43d ≥ -20\) are multiplied by \(34\), which is a positive number, leading to \(34(43)d ≥ -20(34)\).
Thus, the correct response is:
