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).
<h2>
Corect ansver: C) II and III only</h2><h2>

.
Answer:

Step-by-step explanation:

Calculate the derivative of the function:

Calculate the zeros of the derivative:

Let's check the derivative sign:

Sketch a parabola open down
(before the brackets there is the number -3 < 0)
Look at the picture.
Where the derivative is negative, the function decreases.
Where the derivative is positive, the function increases.
Therefore your answer is:

First find midpoint of AB and lastly find the length of midpoint and C
Answer: The graph intersects y = 0 at x = 2 and x = -6, so the answer is B
