Answer:
k = 5 and (6,2).
Step-by-step explanation:
Since (1,-1) is a solution of the equation 3x - ky = 8, so the point (1,-1) will satisfy the equation above.
Hence, putting x = 1 and y = -1 in the equation will give left-hand side = right-hand side.
So, 3(1) - k(-1) = 8
⇒ 3 + k = 8
⇒ k = 5 (Answer)
Therefore, the equation of the straight line is 3x - 5y = 8 ....... (1)
Now, putting x = 6 , then from equation (1) we get y = 2
Therefore, (6,2) is also a point on the graph of equation (1). (Answer)

Answer: 66 water bottles in 3 minutes.
Step-by-step explanation:
First, you see how many times 25 goes into 550.
- Your answer should be 22.(<em>22 is the amount of bottles in a minute</em>)
Next, you multiply 22 by 3 because you want to see how many bottles are produced in 3 minutes.
- Your answer should be 66.(<em>66 is the amount of bottles in 3 minutes</em>).
--- Your final answer is 66 water bottles in 3 minutes.
