X² - 3x - 4 = 0

Reverse FOIL method . . .

(x - 4)(x + 1) = 0

one of the paranthesis has to be equal to zero if the other is not . . .

x - 4 = 0

<u><em>x = 4</em></u>

x + 1 = 0

<u><em>x = -1</em></u>

Answer:

  (1) x(2/3) = y

  (2) 27

  (3) 8

  (4) 9

Step-by-step explanation:

The first line of the table tells you how to fill in the second line. Use the x and y values from the third line to write (y/x) = (2/3). This gives you the equation ...

  x(2/3) = y . . . . line (1)

For the remainder of the table, you can use the given value compared to the value in line 3 to see what the multiplier is for the other value.

(2): The multiplier is 18/2 = 9, so the missing x-value is 3×9 = 27.

(3): The multiplier is 12/3 = 4, so the missing y-value is 2×4 = 8.

(4): The multiplier is 6/2 = 3, so the missing x-value is 3×3 = 9.

In the 1980s land prices in Japan surged upward in a ""speculative bubble."" Land prices then fell for 11 straight years between
Aloiza [94]

Answer:

Step-by-step explanation:

Given the supply of land is perfectly inelastic, the drop in prices must have resulted from decreased demand for land. The demand for land would fall if there were less of a return on the land (i.e., rent), so we can safely assume that land rent fell in Japan between 1990 and 2001. The shifts from D3 to D2 to D1 demonstrate graphically what happened in Japan.
