Consider the following pair of equations: −x − y = −5 y = x + 1 If the two equations are graphed, at what point do the lines rep

Mnenie [13.5K]

-x - y = -5
y = x + 1

-x -(x + 1) = -5
-x - x - 1 = -5
-2x = -5 + 1
-2x = -4
x = -4/-2
x = 2

y = x + 1
y = 2 + 1
y = 3

solution is : (2,3)

A dog breeder plans to mix two types of food to make a mix of low cost

lys-0071 [83]

Answer:

3.75 bags of ChowChow
0.75 bags of Kibble

Step-by-step explanation:

The constraints on protein, minerals, and vitamins give rise to the inequalities ...

40c +30k ≥ 150 . . . . . . required protein

20c +20k ≥ 90 . . . . . . required minerals

10c +30k ≥ 60 . . . . . . . required vitamins

And we want to minimize 10c +12k.

The graph shows the vertices of the feasible region in (c, k) coordinates. The one that minimizes cost is (c, k) = (3.75, 0.75).

To minimize cost, the daily feed should be ...

3.75 bags of ChowChow
0.75 bags of Kibble

Daily cost will be $46.50.
