For this case we have the following expression:
[tex] \frac{10yz}{-2z} [/tex]
Rewriting we have:
[tex] \frac{-5yz}{z} [/tex]
What we must do for this case is to use the properties of exponents to simplify the expression.
We have then:
[tex] -5yz ^ {1-1} [/tex]
Rewriting we have:
[tex] -5yz ^ {0} [/tex]
[tex] -5y (1) [/tex]
[tex] -5y [/tex]
Answer:
The simplified expression is given by:
[tex] -5y [/tex]
option B
