(Note: "Parallelograms" includes rectangles, squares, and rhombussesses.)
Any polygon with more than 4 sides <u>can</u> have at least one pair of parallel sides,
but it's not guaranteed.
The answer I got was y=-12x+43.
Hope this helps!
The amount you save is : $119 (usd im so sorry, i tried to do it in £ but i had a hard time with the different currencies.) so, the sale price is : $51 usd
3x-5y=-15 What you do to one side, you must do to the other.
-<u>3x -3x
</u><u />-5y=-3x-15
<u>-5y</u>=<u>-3x</u> <u>- 15</u>
-5 -5 -5
Final Answer: y=3/5x + 3
