Study Notes
Inequality Problem Overview
- Inequality: (3x + 1 < \frac{4x}{5} + 3)
- Objective: Solve both algebraically and graphically.
Algebraic Solution Steps
- Start with the original inequality: (3x + 1 < \frac{4x}{5} + 3).
- Eliminate the fraction by multiplying the entire inequality by 5: (15x + 5 < 4x + 15).
- Rearrange to isolate (x): (15x - 4x < 15 - 5).
- Simplify to: (11x < 10).
- Divide by 11: (x < \frac{10}{11}).
Interval Notation
- The solution in interval notation: ((- \infty, \frac{10}{11})).
Graphical Representation
- Graph the solution on a number line.
- Shade to the left of (\frac{10}{11}) indicating all values less than (\frac{10}{11}).
- Use an open circle at (\frac{10}{11}) to denote that it's not included in the solution set.
Possible Graph Options
- Analyze and select the correct graph representation from given options (A through F).
