If \(|x| > 5\), is \(|x-5| = 5-x\)
(1) \(-x(x^2) > 0\)
(2) \(x^5 < 0\)
This is a YES or NO question.
Solving the original question stimulus will give us a value of x
-5>x>5
(1) \(-x(x^2) > 0\)
Tells us that x is negative ; Meaning Positive values of x are not allowed -5>x
>5Therefore x<-5
Now, no need to solve, because the answer is will be either a definite Yes or a definite no
SUFFICIENT
(2) \(x^5 < 0\)
Only a negative number raised to an odd power is negative
Again tells us that x is negative; Meaning Positive values of x are not allowed -5>x
>5Therefore x<-5
Now no need to solve, because the answer is will be either a definite Yes or a definite no
SUFFICIENT
ANSWER IS D
