Math Problem Statement

−33>−4x−5or −4x−5≥−49

Solution

We are given two inequalities:

  1. 33>4x5-33 > -4x - 5
  2. 4x549-4x - 5 \geq -49

We need to solve both inequalities individually.

First inequality: 33>4x5-33 > -4x - 5

  1. Add 5 to both sides: 33+5>4x-33 + 5 > -4x 28>4x-28 > -4x

  2. Divide both sides by 4-4. Remember, when dividing by a negative number, the inequality sign reverses: 284<x\frac{-28}{-4} < x 7<x7 < x or x>7x > 7

Second inequality: 4x549-4x - 5 \geq -49

  1. Add 5 to both sides: 4x49+5-4x \geq -49 + 5 4x44-4x \geq -44

  2. Divide both sides by 4-4, reversing the inequality: 4x4444\frac{-4x}{-4} \leq \frac{-44}{-4} x11x \leq 11

Combined solution:

The solution to the compound inequality is: 7<x117 < x \leq 11 or x(7,11]x \in (7, 11]

  4. Solve and graph: 5x10<05x - 10 < 0 and 2x+8122x + 8 \geq 12.
  5. Solve for xx: 4x3>2x+74x - 3 > 2x + 7.

Tip: Always reverse the inequality sign when multiplying or dividing both sides by a negative number.
