With x = -5 and y = 25, all we have to do is replace the values.
(5 |x| - y³)/x
(5 |-5| - 25³)/(-5)
The vertical lines surrounding x are absolute value, or the distance from zero. The function of absolute value is to practically turn it positive, regardless of whether it is negative or positive.
|-5| = 5
|6| = 6
|0| = 0
Absolute value, or these two lines, just make the value inside positive, and it doesn't matter whether the value is negative or positive because it just ends up being positive anyway.
y³ basically is a cube, and expanded, it means y x y x y. It's practically an exponent. With the given values of x = -5 and y = 25, we can just plug the values inside.
(5 |-5| - 25³)/(-5)
Notice how the |-5| turns into 5. Absolute value makes it positive.
(5 x 5 - 25³)/(-5)
(25 - 25³)/(-5)
Then just simplify.
-15600/(-5)
The answer is 3120, or B.
