Answer:

9. C

10. C

9.

simply, \frac{4}{5} >\frac{2}{3}

10.

the greatest divisor of 28 is 7, so:

28 + 7 = 35

11.

the greatest divisor of 15 is 5, so:

15 + 5 = 20

n = 20

the greatest divisor of 20 is 10, so:

20 + 10 = 30

Elden [556K]

Answer:

  1. x ≥ 2009
  2. 3.2x -6222.8
  3. 257.2 mm
  4. year 2100

Step-by-step explanation:

1. The problem statement tells you the function applies for year values (x) 2009 and later. The domain is real numbers greater than or equal to 2009.

__

2. We can use the distributive property to eliminate parentheses:

  3.2(x -2009) +206 = 3.2x -6428.8 +206

  = 3.2x -6222.8

__

3. Put 2025 in the equation and do the arithmetic

  g(2025) = 3.2·2025 -6222.8 = 257.2 . . . . mm

__

4. Put this value of level rise in the equation and solve for x.

  g(x) = 3.2x -6222.8

  500 = 3.2x -6222.8 . . put 500 mm where g(x) is in the equation

  6722.8 = 3.2x . . . . . . . add 6222.8

  x = 6722.8/3.2 = 2100.875

The water rise will be equal to about half a meter late in the year 2100.
