The second equation has a slope of -2 and passes thru the point (3,-2)
What you do is divide 19.5 by 3 which is 6.5. So every bag would weight 6.5 lbs
Its impossible to draw a trapezoid with just three right angles.
a trapezoid has 4 sides, which means all the angles inside the trapezoid must add up to 360 degrees.
if you have just 3 right angles (90x3), you already use up 270 degrees. Leaving you with just 90 degrees left, which is also a right angle. That means, there has to be four, if you have at least 3.
Flip it and itll give you 1.98 but round it and youll get d.x=2
The answer is -1,-8,0,13,67,80
