Answer:

minimum -45, maximum 32

Step-by-step explanation:

C=4x-3y

x≥0, y≥4, x+y≤15

Maximum value of C can be achieved at max x and min y

  • min y=4 => max x=15-4=11
  • C=4*11-3*4= 32

Minimum value of C can be achieved at min x and max y

  • min x=0, max y =15
  • C=4*0-3*15= -45

So answer is minimum -45, maximum 32

Describe the transformation from the graph of f(x)=x+8 to the graph of g(x)=x-3
andreev551 [17]

Answer:

A.)

Step-by-step explanation:

Translations are as follows: Up is + on Y axis, down is - on Y axis. Right is + on X axis and left is - on X axis.

The function f(x) = x+8 is translated to (0,8) since their is no number in a bracket with x (example: f(x)= (x-2)+5 would be (2,5) since the X axis is taken as the opposite sign).

g(x) = x-3 translates to (0,-3) which is 11 units down from f(x)

Answer:

28 meters

Step-by-step explanation:

<u><em>The question in English is</em></u>

On a 32-meter roll of fabric, it cuts an eighth of the total. How many meters of fabric are left in a roll?

step 1

we know that

To find out how many meters of fabric were cut, multiply the total meters by the fraction that was cut

32(\frac{1}{8})=4\ m

step 2

To find out how many meters of fabric are left, subtract the meters of fabric that were cut from the total meters of fabric

so

32-4=28\ m
