It takes 320g of pasta and 200ml of sauce to make one batch of spaghetti, s, and it takes 640 g of pasta and 800ml of sauce to make one batch of lasagna, l. friedrich is a chef who wanrs to make spaghetti and lasagna using no more than 5120g of pasta and no more than 4000 ml of sauce. write a system of inequalities to model the constraints of the situation.
i also need to graph it so if someone can give me a graph that would be a bonus. if you can give me the equations to start with and maybe how to set up the graph, i would be so grateful.
giving me an equation would work tho

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.
