A grocery store charges 2.59 for a single bottle of orange juice. however if customers buy more than one bottle they get every bottle after the first at a reduced price. hannah bought 4 bottles of orange juice and paid a total of $9.76. enter an equation that can be used to determined the total cost, y, in dollars, for x in bottle of orange juice where x > 0.

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.

it would open into a square depending on the type of envelope i’m not sure about the second part
