3. Reduction
For example,
11x - 3y = 69
-3x + 3y = 3
___________
8x + 0y = 72 => x = 72/8 => x = 9 => -27 + 3y = 3 => 3y = 30 => y = 30/3 => y = 10.
Answer:
The incorrect statement is decreasing from (-∞, -1)
Step-by-step explanation:
Intercepts are where it touches the axis
The x intercepts are -2 and 1
Increasing is where it goes up
We are increasing from (-∞, -1) and (1,∞)
Decreasing is where it goes down
We are decreasing from ( -1,1)
The incorrect statement is decreasing from (-∞, -1)
