I. xy + 2y=3 Not linear equation because is grade 2 equation (xy).
II. x-2y = y Are linear equations in two unknowns (x and y).
III. 3x + 2y = 5 Are linear equations in two unknowns (x and y).

Answer:
A. width = x - 4.5
B. 111 = 2(x + (x -4.5))
Step-by-step explanation:
A. The width is 4.5 meters shorter than x, so is x -4.5.
__
B. The perimeter is twice the sum of length and width. It is 111 meters, so an equation for it could be ...
111 = 2(x + (x -4.5))
Answer: The rate of change is 11.6666...
Step-by-step explanation:

Answer:
all values! x ∈ R
Step-by-step explanation:
The derivative f'(x) = 6x²-6x+12 is a parabola opening upward, with its (positive!) minimum at (0.5, 11.5). If the derivative is always positive, the function must be increasing everywhere!
