Aman spent 15 minutes every day feeding the pigs. he spent 3 minutes less in the evening than he did after breakfast. for how many minutes did the man fed the pigs each time?

Let's call the time he spent feeding the pigs after breakfast and the time he spent feeding the pigs in the evening . Using the information in the problem, we can say that , since he spent 3 minutes less than the amount of time at breakfast, which is .

We can also say that , since he spent 15 minutes each day in total feeding the pigs. If we substitute in what we found for , then we can find the equation , which we can simplify, as shown below:

We have found that he spent 9 minutes after breakfast feeding the pigs. We can find by substituting in what we found for into our earlier equation:

He spent 9 minutes feeding the pigs after breakfast and 6 minutes feeding the pigs in the evening.

No, because two points with the same x-value have different y values.

Step-by-step explanation:

The two points in the middle of the graph are (4, 2) and (4, 10). As can be seen, the x-value for both of the points are 4. Functions are when you multiply the x value by the slope (the same number every time) to get the answer for y. You cannot get two different answers by mutliplying the same numbers together.
