Answer:

D

Step-by-step explanation:

Hello There!

N = Nickels and D = Dimes

The total amount of nickels and dimes is 27

so d + n = 27

or d = 27 - n

or n = 27 - d

It says that the amount of nickels she has is 3 times the amount of dimes minus 1

so

n = 3d - 1

so looking at the information above we can conclude that the answer is D

Amy wants to rent a bicycle for the day. The company charges $12 to rent the bike, plus $6 per hour. If Amy has a budget of $42,
Arturiano [62]
Using the equation y=6x+12, where x is the number of hours and y is the total cost for the given value of x, you can plug in 42 for y and solve:

42=6x+12
42-12=6x
30/6=x
5=x

Thus, Amy can rent the bike for 5 hours.

Answer:

The vertex that maximize the problem is (2,000,4,000)

Step-by-step explanation:

we have

z=10x+6y

The vertex of the shaded region are

A(0,0), B(4,000,0),C(2,000,4,000), D(0,6,000)

Substitute the value of x and the value of y of each vertex in the z equation to find the solution

case A) A(0,0)

z=10(0)+6(0)=0

case B)  B(4,000,0)

z=10(4,000)+6(0)=40,000

case C)  C(2,000,4,000)

z=10(2,000)+6(4,000)=44,000

case D)  D(0,6,000)

z=10(0)+6(6,000)=36,000

therefore

The vertex that maximize the problem is (2,000,4,000)
