Answer:

The second set.

Step-by-step explanation:

Consider the first set of ordered pairs.

For an increase of 9 is the x-values the y values increases by 1.

In the case of the second set the increase in y values compared with increase in y values is different:

x = 2-0 = 2, y = 10- 0 = 10. That is 5 units of y for every unit of x.

x = 5-2 = 3, y = 13-10 = 3. That is 1 unit of y for every 1 unit of x.

Answer:

Step-by-step explanation:

Let the 3 numbers be 4x , 5x and 6x

4x + 6x = 5x + 55

10x = 5x + 55 Subtract 5x from both sides.

5x = 55 Divide by 5

x = 55/5

x = 11

Therefore the numbers are

3*11 = 33

4*11 = 44

5*11 = 55

Marvin is comparing two different music websites. Website A charges $10 per month for a subscription and $0.25 per song. Website

Alecsey [184]

Website A:
c = 10 + 0.25 s
where c is the cost and s is the number of songs.
Website B:
c = 0.75 s
The equation ( answer ):
10 + 0.25 s = 0.75 s
We can solve this equation:
10 = 0.5 s
s = 10 : 0.5
s = 20 ( Marvin would have to buy 20 songs to to make the costs equal )

What is the relationship among direct variation,lines,rates of change, and slope?

JulsSmile [24]

A direct variation is a proportional equation. Such as:

For every 3 cookies, linda gets 1 glass of milk. The equation for this is y=3x where y is the glasses and x is the cookies. this is a direct variation. It also has a linear line. Linear means straight. Rate of change and slope are the exact same thing. They are the value of 'm' in y=mx+b
