Answer:
Third option.
Step-by-step explanation:
Some transformations for a function f(x), are:
If 
, the function is shifted down "k" units.
If 
, the function is shifted up "k" units.
If 
, and 
, the functio is stretch vertically by a factor of "b".
If 
, the function is reflected over the x-axis.
Therefore, knowing that the parent function 
was transformated by reflecting it over the x-axis, stretching vertically by a factor of 2 and shifting it down 3 units, we can determine that the following function represents the transformation:
Answer:
x = 1, y = 4
Step-by-step explanation:
This is very simple
Since you have 2 equations with the same coefficient of x, just minus one equation from another:
x + 3y = 13
-
x + 2y = 9
1y = 4
Sub y = 4 into any of the 2 equation,
x + 3(4) = 13
x + 12 = 13
x = 13 - 12
= 1
