It is the transitive property. C It's actually a very good example of the transitive property.

The associative property would be (a + b) + c = a + (b + c) If you add a and b together and then add on c, that's the same thing as adding b + c together and then add a to it.

The Commutitive property would be a + b = b + a. Again it does not matter which entry you put into your calculator first.

The symmetry property is a = b or b = a. They are interchangeable. That's not what you are given.

A new online music service has a collection of 1,500 songs. It expects to triple the number of songs each year for the next few

Rzqust [24]

Answer: y = (3^(x-1))*1500

Step-by-step explanation:

We want the relationship

y = f(x)

where y is the number of songs, and x is the number of years.

We know that in the first year, x = 1, the site has 1,500 songs.

The next year, x = 2, the number of songs is tripled, then we will have:

1,500*3 = 4500 songs.

The next year, x = 3, we will have: 3*(3*1500) = (3^2)*1500.

when x = 4, the number is tripled again:

3*(3^2)*1500 = (3^3)*1500

We already can see the pattern, for the year x, the site will have:

y = (3^(x-1))*1500 songs.

This is the equation we are looking for.

5. The sum of two numbers is 24. Five times the first number minus the second

photoshop1234 [79]

Answer:

6 and 18

Step-by-step explanation:

a+b=24

5a-b=12

5a+a=6a

24+12=36

6a=36 so A on it's own is 6

24-6=b

b=18

The sum of two numbers is "-1" One number is 12 more than the other one. Find the numbers.

ruslelena [56]

Answer:

x = 5.5

y = - 6.5

Step-by-step explanation:

Let one of the numbers = x

Let the other number = y

x + y = - 1

x = y + 12 Put the second equation into the first one

y + 12 + y = - 1 Subtract 12 from both sides

y + y = - 1 - 12 Combine both left and right sides

2y = - 13 Divide by 2

2y/2 = - 13/1

y = - 6.5

x + y = - 1

x - 6.5 = - 1 Add 6.5 to both sides

x = 5.5

Order these numbers for lest to greatest 1/2 ,1.1 ,5/3 ,2, 0 ,0.4, -2 ,5/8

Nat2105 [25]

The least number should always start off with negatives if there are any. In this case there is so we can start with -2 as our least amount. Next are the small fractions. If you're allowed a calculator, I would use that to find what the decimals will look like for each fraction:

$\frac{1}{2} =0.5\\ \\ \frac{5}{3} =1.6666666666666666666666666666667\\ \\ \frac{5}{8} =0.625$

After -2 the next least number is 0 and the next one is the fraction or decimal closest to the number 0 which is 0.4

The next number would be from the fractions we solved earlier. 0.5 and 0.625 would follow 0.4 and then 1.1 and 1.6667(solved for from fraction).

Here is the list:

$-2,0,0.4,\frac{1}{2} ,\frac{5}{8} ,1.1,\frac{5}{3}$

Hope this helps!
