Evaluate the following expression when x = -5 and y = 25.
\frac{5\mid x \mid \ − \ y^{3}}{x}
A.
-3,130
B.
3,120
C.
-630
D.
620
When x = -5 and y = 25, we can substitute these values into the expression to get:
\frac{5\mid -5 \mid \ − \ 25^{3}}{-5}
The absolute value of -5 is 5. Substituting this into the expression, we have:
\frac{5(5) \ − \ 25^{3}}{-5}
Simplifying further, we have:
\frac{25 \ − \ 15625}{-5}
\frac{-15500}{-5}
3100
So the value of the expression when x = -5 and y = 25 is 3100.
The correct answer is:
B. 3,120
