Given:
Which of the following statements is necessarily true?
To solve this problem, we'll follow these steps:
Step 1: Simplify the constants in the inequality.
Step 2: Rearrange the inequality into a solvable form.
Step 3: Analyze the resulting inequality to find the acceptable range of .
Now, let's work through each step:
Step 1: Calculate the absolute values:
- 
- 
So the inequality becomes:
Simplify the constants:
Step 2: Rearrange by isolating :
Step 3: Solve :
The expression  results in the inequality .
Given:
\( \left|2x-1\right|>-10 \)
Which of the following statements is necessarily true?
These are constants that you can calculate immediately! and . Simplifying these makes your inequality much easier to work with.
The absolute value inequality means the distance from d to zero is less than 2. This gives us .
Double-check your arithmetic! We have , which simplifies to , so .
Pick a test value like d = 0: ✓. Try d = 3: ✗, confirming d = 3 is outside our solution.
That would be the solution to , not . Always double-check your final simplified inequality before writing the solution!
