Correct formula is y = kx, where k is the "constant of proportionality."

If y = 9 when x = 2, then 9 = k(2), or k = 9/2.

Then y = (9/2)x.

If x = 3, y = (9/2)(3) = 27/2  (answer)

Answer:

y = 2500x -4989000

Step-by-step explanation:

To find the slope we use the formula

m = (y2-y1)/(x2-x1)

   = (31000-26000)/(2008-2006)

   =5000/2

 2500

The slope is 2500

Then we use point slope form to write an equation

y-y1 = m(x-x1)

y-26000 =2500(x-2006)

Distribute

y-26000 = 2500x -5015000

Add 26000 to each side

y-26000+26000 = 2500x -5015000+26000

y = 2500x -4989000

3, 12, 48, 192, 768, . . .
Sav [38]
The answer would be the sequence has a common ratio of 4.
The explanation for this would be:
To get the common ratio for get the simplest form of the two numbers, so 12/3 = 4 and 48/12 = 4So we know that their common ratio is 4.
To check:
3 x 4 = 12
12 x 4 = 48
48 x 4 = 192
192 x 4 = 768

The triangles are similar.

25/5 = 5
and also 
15/3 = 5
so
(3x+ 8)/5 = 4
3x + 8 = 20
3x = 12
  x = 12/3
  x = 4

answer is x = 4

If D is the center of the circle below and AC measures 48, what is the measure of ABC
dimulka [17.4K]

Answer:

24

Step-by-step explanation:

How do we know that a circle must complete up to 180, then we have to:

180 - 48 = 132

Now knowing this distance we can also know the other, starting from the same concept, in addition to what the circle below is like, a semicircle refers to so we divide by 2:

(180-132) / 2 = 24

Therefore the answer is 24.

We can also do it ABC is half of ADC. So ABC = 48/2 = 24
