Answer: i think the answer is B for number 1

Step-by-step explanation:

Answer:

1.

The slope is : [tex]\frac{8.4-4.2}{2-1}[/tex] = 4.2

[tex]\frac{12.6-8.4}{3-2}[/tex] = 4.2

We can see that the distance is same each time.

Hence, the equation that represents the relationship between the distance traveled and the elapsed time is [tex]f=4.2p[/tex]

2.

Let the amount of money needed be = z

Total bags purchased = n

Cost of 1 bag = $1.58

So, the required equation is :

[tex]z=1.58n[/tex]

3.

When rainfall increases, the water level in the lake goes up. Rainfall is the independent variable in this situation. This is True.

Here the water level is dependent on the amount of rainfall so water level is dependent and rainfall is independent. Rainfall is not dependent on the water level in a lake.

4.

Let y represents the distance the plane has traveled.

Let z represents the time it has spent traveling.

distance = speed x time

So, [tex]y=600z[/tex]

5.

Diana can earn money for the tickets she sells. Here tickets are independent and money earned is dependent on the number of tickets sold. The more tickets sold, the more money Diana can earn.

So, the answer is : C: The number of tickets sold is the independent variable because it affects the amount of money earned.
