Turn both equations into slope-intercept form [ y = mx + b ].

x + 3y = 3

~Subtract x to both sides

3y = 3 - x

~Divide 3 to everything

y = 1 - x/3

~Reorder

y = -1/3x + 1

4x + 3y = -6

~Subtract 4x to both sides

3y = -6 - 4x

~Divide 3 to everything

y = -2 - 4x/3

~Reorder

y = -4/3x - 2

Graph of the equations will be shown below. Note that the solution of graphing two equations will be where both equations intersect. Both lines intersect at (-3, 2), hence making that the solution.

Best of Luck!

XYZ Corporation operates two plants, each of which has a capacity of 100 units per day. Each day, XYZ must ship their product to
Strike441 [17]

9514 1404 393

Answer:

  1. {20, 20, 20, 40} units to {A, B, C, D}
  2. {0, 0, 0, 100}

  minimum shipping cost: 3000

Step-by-step explanation:

In general, shipping costs more from Plant 1. The excess costs to ship to customers A, B, C, D are, respectively, (24-18) = 6, (21-16) = 5, (19-19) = 0, (18-10) = 8.

The greatest excess cost is for shipping to customer D from plant 1, so we want to ship as many units as possible to customer D from plant 2.

Shipments from Plant 2 to Customers {A, B, C, D} = {0, 0, 0, 100}.

Then the remaining shipments are fulfilled from Plant 1.

Shipments from Plant 1 to Customers {A, B, C, D} = {20, 20, 20, 40}.

The amount spent on shipping each day is ...

  100×10 +20×24 +20×21 +20×19 +40×18

  = 20×(50 +24 +21 +19 +36) = 3000 . . . . daily shipping cost

Let R be the greater radius and r be the smaller radius

A) Area of the sidewalk = R^2 - r^2 - This can be the expression

B) = 3.14
=(R^2-r^2)
=(11^2-9^2)
=(121-81)
=*40

That was the simplified expression

Answer = 3.14 * 40 = 125.6m^2
