Answer:
B. 0
Step-by-step explanation:
2-2/5-2= 0/3= 0
Another way to look at this is that because they have the same y coordinate, it must simply be a horizontal line, which has a slope of 0
<span>Here is the real life situation that goes with c = 40/h... You have 40 cupcakes. You give the same number of cupcakes to "h" number of people. How many cupcakes does each person have? Let c be the number of cupcakes for each person</span>
Answer:
$8
Step-by-step explanation:

Answer:
4/5
Step-by-step explanation:
1/2= 5/10
3/10+5/10=8/10
8/10= 4/5
Answer:
There are no extraneous solutions
Reasoning:
An extraneous solution is a solution that isn't valid, it might be imaginary like the square root of a negative number.
first we want to isolate z:
1+sqrt(z)=sqrt(z+5)
^2 all ^2 all
(1+sqrt(z))(1+sqrt(z))=z+5
expand
1+2sqrt(z)+z=z+5
-1 -z -z -1
2sqrt(z)=4
/2 /2
sqrt(z)=2
^2 all ^2 all
z=4
Since there is one solution and it is a real number, there are no extraneous solutions.
