2<4
What is the inequality of: x - 4 < 6
-8
-4
4
That already IS the inequality.
x^4 is not an inequality. (An inequality has a "bigger than or equal to/less than or equal to/less than/bigger than" sign involved. I.e not an "equals" sign, since this would be an "equality"). But x^4 is not an equality, nor an inequality.
There can be no answer because there is no inequality in the question.
4 & |-4|
-4 < 9
0
No, it is an expression.
The inequality appears to be incomplete; it seems like there may be a missing operator or context (e.g., "x < 4," "x > 4," etc.). However, if we interpret it as "x < 4," then -4 is indeed a solution, as -4 is less than 4. If you can clarify the complete inequality, I can provide a more specific answer.
