Math Problem Statement

Solve and graph: 7x + 4 < 4x + 10 AND 2 + 6x ≤ 11x + 7

Solution

The problem in the image contains a system of inequalities to solve and graph:

  1. 7x+4<4x+107x + 4 < 4x + 10
  2. 2+6x11x+72 + 6x \leq 11x + 7

Let's solve each inequality step-by-step.

Inequality 1: 7x+4<4x+107x + 4 < 4x + 10

  1. Subtract 4x4x from both sides: 7x4x+4<107x - 4x + 4 < 10 3x+4<103x + 4 < 10

  2. Subtract 4 from both sides: 3x<63x < 6

  3. Divide by 3: x<2x < 2

Inequality 2: 2+6x11x+72 + 6x \leq 11x + 7

  1. Subtract 6x6x from both sides: 25x+72 \leq 5x + 7

  2. Subtract 7 from both sides: 55x-5 \leq 5x

  3. Divide by 5: 1x-1 \leq x

Combined Solution:

The solution to the system of inequalities is: 1x<2-1 \leq x < 2

Graphing:

On the number line:

  • A closed circle at x=1x = -1 because x1x \geq -1 (it includes -1).
  • An open circle at x=2x = 2 because x<2x < 2 (it does not include 2).
  • A line connecting the points from x=1x = -1 to x=2x = 2.
