A project coordinator is tracking the completion time of two phases of a software update. Phase 1 takes (3y)/(4y - 3) hours and Phase 2 takes 7/(4y - 3) hours. Which of the following represents the correct sum of these two expressions?

A quality control technician is calculating the total defect rate from two different production lines. The rate for Line A is 3y / (4y - 3) and the rate for Line B is 7 / (4y - 3). When the technician adds these two rates together, the numerator of the resulting expression is ____.

A site supervisor is combining two material density requirements represented by the expressions $\frac{3y}{4y-3}$ and $\frac{7}{4y-3}$. True or False: To find the correct sum of these two expressions, the supervisor should add the numerators together and keep the common denominator $4y-3$ for the resulting expression.

Documentation of Rational Expression Addition for Performance Metrics

A technical auditor is reviewing a spreadsheet that calculates a department's efficiency rating by adding two rational expressions: $\frac{3y}{4y - 3}$ and $\frac{7}{4y - 3}$. After combining the numerators to reach the expression $\frac{3y + 7}{4y - 3}$, what is the next standard step required to complete the calculation according to algebraic rules?

A workforce scheduler is combining two shift-length coefficients represented by the expressions $\frac{3y}{4y-3}$ and $\frac{7}{4y-3}$. According to the rule for adding rational expressions with a common denominator, which of the following is the denominator of the resulting sum?
