Answer: 
Step-by-step explanation:
Given the inequality 
, we need to solve for "x".
We can subtract 
to both sides:
(This step is shown in the exercise)
Now, we can add 10 to both sides:
(This step is not shown in the exercise)
And finally, divide both sides by -3:
(This is shown in the exercise)
Therefore, the missing step is:
39
Divide 78 by 2 to get 39 and add in to the number
The volume is 800pi cubic feet
Slope formula:
y2-y1
-------
x2-x1
48)
1-3 -2
---- = ----
-2-4 -6
So the slope of MN is 1/3
