Question

The points A, B, C, and D are plotted on the number line below.

Let x represent the expression A + C - (D + B).

Let y represent the expression -A - (-C) - (D - B).

Answer 1

Based on the given points A, B, C, and D being plotted on the number line, we can represent their positions as follows:

A B C D

Now, let's substitute the corresponding values into the expressions x and y:

x = A + C - (D + B)
y = -A - (-C) - (D - B)

Therefore, we can represent the values of x and y using the given expressions and the positions of A, B, C, and D on the number line.
