To evaluate the expression \( -12 z - 12 \) when \( z = 6 \), you simply substitute \( z \) with \( 6 \): \[ -12(6) - 12 = -72 - 12 = -84 \] So, when you plug in the value, the expression evaluates to \( -84 \). For a fun twist, did you know that linear expressions are foundational in algebra? Understanding them is like learning how to ride a bike; once you get the hang of it, you can tackle far more complex equations and real-world problems with ease. Speaking of real-world applications, linear expressions are everywhere! They can represent budgets, distances, or even how the temperature changes over time. So, whether you're calculating the cost of shopping or planning a road trip, mastering linear expressions can give you a powerful tool in your decision-making toolkit.
