Rework problem 1 in section 1 of Chapter 7 of your textbook, about Sam's Deli, using the following data. Assume that each small sandwich uses 5 inches of bread and 4 ounces of meat, and that each large sandwich uses 12 inches of bread and 8 ounces of meat. Assume also that the Deli has on hand each day 120 feet of bread and 45 pounds of meat. Assume also that the profit on each small sandwich is $1.20 and the profit on each large sandwich is $1.50. How many sandwiches of each size should the Deli make in order maximize its profit

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
