Answer:

45 minutes

Step-by-step explanation:

Given:

Your friends piano lesson lasts 15 minutes longer than your piano lesson.

You have 6 lessons per month and your friend has 4 lessons per month.

At the end of the month, your time spent at piano lessons is the same as your friends time.

Question asked:

How may minutes is your friends piano lesson ?

Solution:

Let your piano lesson in minutes = x

Then your friend's piano lesson will be = x+15

As you have 6 lessons per month, it contains total minutes:-

1 lesson = x\ minutes

6 lessons = x\times6=6x\ minutes

As your friend has 4 lessons, it contains total minutes:-

1 lesson = x+15\ minutes

4 lessons =  4(x+15)=4x+60\ minutes

At the end of the month, time spent at piano is same:-

6x=4x+60\\ \\ Subtracting\ both\ sides\ by\ 4x\\ \\ 6x-4x=4x-4x+60\\ \\ 2x=60\\ \\ Dividing\  both\ sides\ by\ 2\\ \\ \frac{2x}{2} =\frac{60}{2} \\ \\ x=30\ minutes

Your piano lesson in minutes = x = 30 minutes.

Your friend's piano lesson will be = x+15 = 30 + 15 = 45 minutes

Therefore, 45 minutes is your friends piano lesson.

Answer:

A. For each input value, x, there is exactly one output value, y.

Step-by-step explanation:

A function always have exactly one output value (y-value) that is related or assigned to each input value (x-value), however, two different x-values can have the same y-value.

In the graph given, although two different values have the same y-value, every x-value has exactly one y-value corresponding to it. No x-value has two different y-values.

Therefore, the graph represents a function.
