If $$|x| > 5$$, is $$|x-5| = 5-x$$

(1) $$-x(x^2) > 0$$
(2) $$x^5 < 0$$

I solved this problem and ended up with a different answer. I believe the correct answer should be E.

Any thoughts ???

I think it is D. The question is basically if x < 0 i.e x is negative. Either A or B tells us x is negative.

For $$|x-5| = 5-x$$, it is required that x-5<0 >>> x < 5

From 1 : x^2 is always positive, so -x needs to be positive , so that $$-x(x^2) > 0$$. Therefore x is a negative number, Also from the question $$|x| > 5$$, So x < - 5. SUFFICIENT

From 2 : x^5 is negative, so x needs to be negative, Also from the question $$|x| > 5$$, So x < -5. SUFFICIENT

it's D

Why do you think it should be E?

My bad. I misinterpreted the question.

From the question, $$|x|>5$$, I interpreted that x should be strictly less than -5 to satisfy the condition -- $$Is |x-5| = 5 - x$$.

But the two answer options note that x is negative but not strictly less than -5 hence I thought option E is the correct.

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>5
Therefore 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>5
Therefore x<-5
Now no need to solve, because the answer is will be either a definite Yes or a definite no
SUFFICIENT

when the given if statement is solved

only one case will be applicable to both the conditions which is x < -5 and not x > 5(when this is used both the statements wont be true)

Just use this to satisfy both the statements
