Question

Set up each situation and simplify if possible. Then, choose all situations that are best modeled by a rational inequality.

Answer 1

Problem: 3x/5x + 5 ≤ 8 + 2x

Solution: x ≥ -15/7

Explanation:

Example of this inequality is:

3x/5x + 5 ≤ 8 + 2x

3x/5x - 2x ≤ 8 - 5

(3x - 10x)/5 ≤ 3

-7x ≤ 15

x ≥ -15/7
