A business manager is using the inequality ${}6x < 10x + 19$ to compare two different service contracts based on the number of hours $x$. Arrange the following steps for solving this inequality in their correct chronological order.

An operations coordinator is evaluating two logistics plans where the cost difference is modeled by the inequality ${}6x < 10x + 19$, where $x$ represents the number of shipments. After simplifying the variable terms to the left side, the coordinator reaches the step: $-4x < 19$. According to the rules for solving inequalities, what must happen to the inequality symbol when dividing both sides by -4 to isolate $x$?

A logistics coordinator is evaluating two shipping providers where the cost comparison is modeled by the inequality ${}6x < 10x + 19$, where $x$ represents the number of packages. True or False: The solution to this inequality, when expressed in interval notation, is $(-\frac{19}{4}, \infty)$.

A procurement specialist is evaluating two shipping contracts where the cost comparison is modeled by the inequality ${}6x < 10x + 19$, with $x$ representing the hours of service. Match each component of the solution process with its corresponding mathematical result or required action.

A project manager is analyzing the cost comparison inequality ${}6x < 10x + 19$ to determine the most cost-effective software license based on $x$ users. After collecting the variable terms, the inequality simplifies to $-4x < 19$. To isolate $x$, the manager divides both sides by $-4$. According to the rules of inequalities, the manager must ____ the direction of the inequality symbol.
