Match the inequality which does not have the given solution set.
Answer to Problem 59PFA
Option
Explanation of Solution
Given:
Solution set:
4 Options of inequality:
Concept Used:
An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value. a ≠ b says that a is not equal to b. a < b says that a is less than b. a > b says that a is greater than b.
There are four different types of inequalities:
Greater than −
For Inequality equation: If
Rules for solving inequality equations:
These things do not affect the direction of the inequality:
- Add (or subtract) a number from both sides
- Multiply (or divide) both sides by a positive number
- Simplify a side
But these things do change the direction of the inequality ("
- Multiply (or divide) both sides by a negative number
- Swapping left and right hand sides
If there is a parenthesis
If there is a bracket
Calculation:
Solve for each options:
Options | Steps | Explanation |
A | Subtract 10x from both sides Added 1 to both sides. Multiply with (− 1 ) both sides and inequality reverses. Option A is correct. | |
B | Subtract 10x from both sides Subtracted 1 to both sides. Multiply with ( − 1 ) both sides and inequality reverses. Option B is not correct. | |
C | Subtract 9x from both sides Subtracted 1 to both sides. Option C is correct | |
D | Subtract 9x from both sides Subtracted 1 to both sides. Option D is correct |
Option
The Others options A , C and D has the solution
Option
Thus, option
