zlopas [31]

Answer:

M + W <= 40

M >= 12

M >= 15

Total profit =  $26 * M + $14 * W

Step-by-step explanation:

Let the number of men be denoted by M

number of women be denoted by W

Maximum no of people that can go one trip = 40

Therefore representing it mathematically we have

M + W <= 40  -------------- CONSTRAINT 1

Minimum number of men needed on trip = 12

Therefore representing it mathematically we have

M >= 12  CONSTRAINT 2

Minimum number of women needed on trip = 15

Therefore representing it mathematically we have

M >= 15  CONSTRAINT  3

profit on 1 man = $26

profit on M men = $26 * M

profit on 1 woman = $14

profit on M men = $14 * W

Total profit combining for men and women =

 $26 * M + $14 * W  -------------CONSTRAINT  4

___________________________________________

writing together all the constraint

M + W <= 40

M >= 12

M >= 15

Total profit =  $26 * M + $14 * W

Solve the following for y: 9x − 3y = 18 (5 points) y = 3x + 6 y = 3x − 6 y = −3x − 6 y = −3x + 6
choli [55]

Answer:

y = 3x - 6

Step-by-step explanation:

given 9x - 3y = 18

isolate - 3y by subtracting 9x from both sides of the equation

- 3y = 18 - 9x ( divide all terms by - 3 )

y = \frac{18}{-3} - \frac{9x}{-3}

  = - 6 + 3x = 3x - 6
