Is the inequality -2(2x + 9) > -4x + 9 sometimes, always, or never true?
Solution:
Given inequality -2(2x + 9) > -4x + 9
In order to check the condition, we need to make the number of terms equal
Using distributive law, multiply -2 with the terms in brackets
We get, -4x - 18 > -4x - 9
Add 4x on both sides
-4x - 18 + 4x > -4x - 9 + 4x
Here, -4x and +4x gets cancelled
-18 > -9
This inequality is always false since -18 is always less than -9
Is the inequality -2(2x + 9) > -4x + 9 sometimes, always, or never true?
Summary:
The inequality -2(2x + 9) > -4x + 9 is never true.
