Answer:
and 
Step-by-step explanation:
First, we are told "sum of 5 times one number, x, and 4 times a second number, y, is 75":
(1)
Then, we are told "he sum of the two numbers is 18":
(2)
At this point we have our system of equations and now we are able to find the values of
and
.
So, let's begin by isolating
from (2):
(3)
Substituting (3) in (1):
(4)
Finding
:
(5) This is the value of 
Substituting (5) in (1):

Answer:
option D

Step-by-step explanation:
An expression is undefined when you get division by zero or in simple words when denominator is zero.
Now we will solve each expression one be one by plugging value of x = 0
<h3>1)</h3><h3>

</h3>

-4/-3 = 4/3
<h3>2)</h3><h3>

</h3>

0/-3 = 0
<h3>3)</h3>


6/1
6
<h3>4)</h3>


<h3>-8/0</h3><h3>undefined</h3>
I would say 504 basing it off of converting 2/3 into 4/6 and used sets of 84 to each be 1/6
