Math Problem Statement

Write An inequality to describe each of the following graphs;then write An equivalente negated inequality

Write an inequality to describe each of the following graphs; then write an equivalent negated inequality.

Solution

The number line graph you provided shows a range between two points:

  • The range starts at 3-3 (closed dot) and goes to 44 (open dot).
  • The arrow heads indicate the inequality involves numbers between 3-3 and 44.

1. The Inequality:

Since the graph shows that 3-3 is included (closed dot) and 44 is not included (open dot), the inequality describing this is: 3x<4-3 \leq x < 4 This inequality describes the set of numbers between 3-3 (inclusive) and 44 (exclusive).

2. The Negated Inequality:

The negation of the inequality involves values outside the range from 3-3 to 44. Negating 3x<4-3 \leq x < 4 gives: x<3orx4x < -3 \quad \text{or} \quad x \geq 4 This is because the negation means the values are either less than 3-3 or greater than or equal to 44.


Would you like any further explanation on inequalities or negations? Here are five related questions you might explore:

  1. How do you represent an inequality on a number line when both endpoints are inclusive?
  2. How do you negate a compound inequality involving "or" statements?
  3. Can you solve real-life problems using inequalities?
  4. What are the differences between strict and non-strict inequalities?
  5. How does interval notation correspond to inequality notation?

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