To solve, your equation would be 2x - 2 >/= 8. You add 2 to both sides, getting 2x >/= 10. Then divide by two on both sides, your answer would be x >/= 5. (x is greater than or equal to 5).
Answer:
2580 ft-lb
Step-by-step explanation:
Water leaks out of the bucket at a rate of 
Work done required to pull the bucket to the top of the well is given by integral
Here, function 
is the total weight of the bucket and water 
feet above the bottom of the well. That is,
is the initial height and 
is the maximum height of well. That is,
Find the work done as,
![&\left.=46x-0.05 x^{2}\right]_{0}^{60}](https://tex.z-dn.net/?f=%26%5Cleft.%3D46x-0.05%20x%5E%7B2%7D%5Cright%5D_%7B0%7D%5E%7B60%7D)
Hence, the work done required to pull the bucket to the top of the well is 
You are trying to solve for k (get k by itself)
-5k - 19 = 5 - 13k Add 19 on both sides
-5k - 19 + 19 = 5 - 13k + 19
-5k = 24 - 13k Add 13k on both sides
-5k + 13k = 24 - 13k + 13k
8k = 24 Divide 8 on both sides
k = 3
