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>
7/10-1/2 in simple form. so the two fractions have different denominators so you need to multiply both denominators 10x2 = 20 so both fractions have 20 on the bottom so they are like this now: 7/20-1/20= 6/20 simplify by 2: 6/20 divide by 2/2 =3/10. 3/10 is your answer
X=20
180-77=103
so then simplify (6x-17)=103
6x=120
x=20
Answer:
24%
Step-by-step explanation:
25 - 19 = 6
25 = 100%
2.5 = 10%
1.25 = 5%
0.25 = 1%
5 = 20%
1 = 4%
6 = 24%
Hope this helps :)
