Answer:
Step-by-step explanation:
The zero of a function is also known as the x-intercept of a function. The x-intercept of a function exists where y = 0. So we will begin by setting each of those lines = 0:
4x - 20 = 0 and -1/2x + k = 0 and then solve each for x:
4x = 20 so
x = 5 and
-1/2x = -k and
1/2x = k so
x = 2k. Now we set the 2 x expressions equal to each other and solve for k:
5 = 2k so
k = 5/2
I'm gonna need you to provide the entire problem. There is not enough information here.
Answer:
See attachment
Step-by-step explanation:
The table that represent a direct variation is shown in the attachment.
To determine a direct variation from tables, you need to inspect the y-intercept of each table.
If there is a table with y-intercept of 0, then it represents a direct variation.
Or you could check the table with equation of the form: 
if you cannot see zero in the y-intercepts directly
Answer:
Depends on what x represents.

Answer:
20% is 8 of 40
Step-by-step explanation:
The answer is actually very simple because all you have to do is multiply 20% by 40.
Therefore
A=8
I hope this helped.
