32-20 = 12

14-2 = 12

so the input is 12 more than the output

so 6+12 = 18

and

-10-12 = -22

Find the minimum value of C=2x+y subject to the following constraints: <br> Please help me!!

-BARSIC- [3]

Answer:

The minimum value of C is 20

Step-by-step explanation:

we have

$2x+3y\geq 24$ ----> constraint A

$4x+y\geq 38$ ----> constraint B

$x\geq 0$ ----> constraint C

$y\geq 0$ ----> constraint D

Using a graphing tool

The solution set of the constraints is the shaded area

see the attached figure

The vertices of the shaded area are (0,38),(9,2) and (12,0)

To determine the minimum value of C substitute the values of x and y of each vertex in the objective function and then compare the results

$C=2x+y$

For (0,38) ---> $C=2(0)+38=38$

For (9,2) ---> $C=2(9)+2=20$

For (12,0) ---> $C=2(12)+0=24$

therefore

The minimum value of C is 20

Dominique can ice cupcakes twice as fast as Houston. When they work together, Dominique and Houston can ice a large order of cup

olganol [36]

This is a work problem. It can be solved as follows:

Houston = 1/x
Dominique = (1/2x)
Together = 1/5

Then, we add Houston and Dominique:

1/x + 1/2x = 1/5

Solve for x,

x = 2/15

Therefore, it would take 15/2 hours for Houston to ice by himself, the last option.
