Math Problem Statement

−3x−10>11or −34≤−3x−10

Solution

Let's solve the inequalities step by step.

1. Solve 3x10>11-3x - 10 > 11:

3x10>11-3x - 10 > 11 First, add 10 to both sides: 3x>21-3x > 21 Now, divide both sides by 3-3. Remember, when dividing by a negative number, you must flip the inequality sign: x<7x < -7 So, the solution to the first inequality is: x<7x < -7

2. Solve 343x10-34 \leq -3x - 10:

343x10-34 \leq -3x - 10 First, add 10 to both sides: 243x-24 \leq -3x Now, divide both sides by 3-3, and flip the inequality sign: 8xorx88 \geq x \quad \text{or} \quad x \leq 8 So, the solution to the second inequality is: x8x \leq 8

3. Final Solution:

The inequality is an "or" condition. Therefore, the solution is: x<7orx8x < -7 \quad \text{or} \quad x \leq 8 Since x<7x < -7 and x8x \leq 8 both include values, the combined solution is: x(,7)(,8]x \in (-\infty, -7) \cup (-\infty, 8]

  2. How do we solve inequalities with absolute values?
  3. How do graphing solutions of inequalities look on a number line?
  4. What if one of the inequalities was a strict equality, how would it change the solution?
  5. What methods can we use to check the correctness of inequality solutions?

Tip: When solving inequalities, always remember to reverse the inequality sign when multiplying or dividing by a negative number.
