Here is the completed table:
Hours Weeks
168 1
1008 6
840 5
<h3>How to complete the table? </h3>
The mathematical operation that would be used to determine the missing values are division and multiplication. In order to convert hours to weeks, divide by 168 hours. To convert weeks to hours, multiply by 168.
1008 hours to weeks = 1008 / 168 = 6 weeks
5 weeks to hours = 5 x 168 = 840 hours

1 hour = 60 minutes
2 hours = 120 minutes
3 hours = 180 minutes
4 hours = 240 minutes
5 hours = 300 minutes
(5 hours) x (60 minutes / 1hour) = 300 minutes
5 x 60 = 300
Answer:
Look below.
Step-by-step explanation:
K(x)=x^2 isnt graphed but P(x)=x^2+n is. We could use this information to figure out what n is. In a quadratic function we always have the same points unless we are transforming it.
X Y
2 4
1 1
0 0
-1 1
-2 4
If we compare what the points were in the parent function to what is shown now we could see that the graph went down 6. From this information we can conclude that n must be -6.
4y - 5x = 9
x = 4y + 11
We can substitute this value of x in the first equation:
4y - 5(4y+11) = 9
4y - 20y - 55 = 9
16y = -64
y = -4
x = 4y + 11
x = -16 + 11
x = -5
