A lot of numbers, equations, etc equal 14.1. Be more specific in your questions. I’m sorry this doesn’t really help but just use this for future reference
180° rotation about the origin changes the signs of the coordinates.
(x, y) → (-x, -y)
It is a reflection over the y-axis and a reflection over the x-axis (in either order).

Answer: B) $1.75</h3>
===================================================
Explanation:
To get the unit cost, we divide the total cost over the number of pounds.
We can do this for any row
- row one: ($17.50)/(10) = $1.75
- row two: ($35.00)/(20) = $1.75
- row three: ($52.50)/(30) = $1.75
- row four: ($70.00)/(40) = $1.75
You don't need to show all four row calculations. You can simply pick one row.
This tells us that each pound costs $1.75
Put another way: the price is $1.75 per pound

The partial derivatives are not equal, so the equation is not exact.
