The perimeter of a rectangle is given by the formula,

We substitute,
and

into the above formula to obtain the expression,


We now group the x and y terms on the Left Hand Side of the equation to get.


We now divide through by 2 to get,

Therefore the width of the rectangle is

Answer:
b
Step-by-step explanation:
I think its 1000 numbers because there from 1 to 999 there are 999 numbers, and then you add zero because it is also a whole number.
The translation, <span> (x, y) → (x + 3, y – 2), means that the point on the X-axis would move 3, and because it's positive, it would move to the right 3.
Y</span>– 2 means the point on the Y-axis moves 2, and because it is negative 2 it moves down 2
