The final answer is (2,1).

Step 1: Solve for either x or y in one of the two equations.

     x + 3y = 5
         - 3y  - 3y
----------------------
     x = -3y + 5
  

Step 2: Substitute the expression you got for x into the opposite equation.

-3y + 5 - 3y = -1
  -6y + 5 = -1
         - 5    - 5
--------------------
  -6y = -6
 ------  -----
  -6       6
 
    y = 1


Step 3: Plug in the solution you got for y into either of the 2 equations.

x + 3(1) = 5
  x + 3 = 5
      - 3  - 3
---------------
  x = 2

Researchers have concluded that a dry basin began to fill with water in 1880. the water level rose an average of 1.6 millimeters
docker41 [41]

Answer:

  1. the domain is [0,129]
  2. 112 mm
  3. 1942

Step-by-step explanation:

1. The function is good for years 1880 to 2009, 0 to 129 years after 1880. Values of x can be anything in the domain [0, 129].

__

2. 1950 -1880 = 70. The year 1950 corresponds to x=70, so the function tells us the water level rose ...

  f(70) = 1.6·70 = 112 . . . . . mm

__

3. We want to find x when f(x) = 100. That will be the solution to ...

  100 = 1.6x

  100/1.6 = x = 62.5

Then 62.5 years after 1880 is year 1942.5. The water level was 100 mm higher than in 1880 in the year 1942.
