Procedure for Solving Absolute Value Inequalities with $>$ or $\geq$

As a quality control technician, you are configuring an automated sorting machine to reject manufactured components that deviate too far from their target specifications. The machine's rejection criteria is represented by the absolute value inequality $|u| \geq a$, where $u$ represents the component's measurement and $a$ is a positive real number representing the maximum acceptable deviation. To properly program the machine's logic parameters, you must translate this formula. Which of the following compound inequalities correctly represents this rule?

In a logistics facility, a quality control technician is configuring an automated sorting machine. The machine is programmed to reject any mechanical component where the measurement deviation $w$ satisfies the absolute value inequality $|w| \geq 10$. To verify the software's logic, match each mathematical term or description with its correct algebraic or geometric equivalent.

An HVAC technician is monitoring pressure fluctuations in a commercial boiler system. The safety parameters require an alert if the pressure deviation $p$ satisfies the absolute value inequality $|p| > 15$. True or False: Geometrically, the solution to this inequality is represented on a number line as two separate, non-overlapping regions that extend infinitely outward in opposite directions from ${}-15$ and ${}15$.

An HVAC technician is configuring a safety system that triggers an alarm if the pressure deviation $p$ satisfies the absolute value inequality $|p| \geq 15$. To program the digital controller, the technician must enter the two equivalent conditions that define this safety range. If the upper condition is $p \geq 15$, complete the lower condition: $p \leq$ ____.

Logistics Quality Control Logic

At a commercial food packaging facility, a quality control technician is training an apprentice to program the automated sorting line. The system is configured to flag any package whose weight deviation $w$ from the target weight exceeds the tolerance limit $t$ (where $t$ is a positive constant). This rejection threshold is represented by the absolute value inequality $|w| \geq t$. Arrange the following steps in the correct order to guide the apprentice from the initial inequality to its complete algebraic and geometric representation.
