Question

Can someone help me with this

Answer 1

Answer is b -5y :) hope this helps

Answer 2

For this case we have the following expression:

$\frac{10yz}{-2z}$

Rewriting we have:

$\frac{-5yz}{z}$

What we must do for this case is to use the properties of exponents to simplify the expression.

We have then:

$-5yz ^ {1-1}$

Rewriting we have:

$-5yz ^ {0}$

$-5y (1)$

$-5y$

Answer:

The simplified expression is given by:

$-5y$

option B
