Answer

The solution set is \( x \leq \frac{11}{13} \), which in interval notation is \( (-\infty, \frac{11}{13}] \).

Solution

We begin with the inequality:   –(3/4)x ≥ –(11/12) + (1/3)x Step 1. Subtract (1/3)x from both sides to gather the x terms:   –(3/4)x – (1/3)x ≥ –(11/12) Step 2. Find a common denominator for the coefficients on the left. The least common denominator for 4 and 3 is 12:   –(3/4)x = –(9/12)x   and  –(1/3)x = –(4/12)x Thus, combining:   –(9/12)x – (4/12)x = –(13/12)x So the inequality now is:   –(13/12)x ≥ –(11/12) Step 3. Multiply both sides by 12 to eliminate the fractions:   –13x ≥ –11 Step 4. Divide both sides by –13. Remember, dividing by a negative number reverses the inequality sign:   x ≤ (–11)/(–13) Simplify the division:   x ≤ 11/13 The solution set in interval notation is:   (–∞, 11/13] Graphing Instructions: 1. Draw a number line. 2. Place a closed circle (or a filled-in dot) at 11/13 to indicate that the number is included. 3. Shade the region to the left of 11/13, representing all numbers less than or equal to 11/13. Thus, the correct answer is: A. The solution set is (–∞, 11/13].

The Deep Dive

To solve the inequality, first, we need to isolate \( x \). Start by getting all terms involving \( x \) on one side and constants on the other: 1. Rewrite the inequality: \[ -\frac{3}{4} x + \frac{1}{3} x \geq -\frac{11}{12} \] 2. Find a common denominator for the \( x \) terms, which is 12: \[ -\frac{9}{12} x + \frac{4}{12} x \geq -\frac{11}{12} \] 3. Combine the \( x \) terms: \[ -\frac{5}{12} x \geq -\frac{11}{12} \] 4. Multiply both sides by -12/5 (remember to reverse the inequality because you are multiplying by a negative): \[ x \leq \frac{11}{5} \] The solution set in interval notation is: \[ (-\infty, \frac{11}{5}] \] Now, for the graph of the solution set, you would shade everything to the left of and including \( \frac{11}{5} \) on a number line. You would mark \( \frac{11}{5} \) with a solid dot to indicate that it is included in the solution set.
