A construction company completes two projects. The first project has $3,000 in labor expenses for 60 hours worked, while the sec

ond project has $2,100 in labor expenses for 42 hours worked. The relationship between the company’s labor expenses and hours worked is linear. Which of the following would correctly calculate the y-intercept of the linear equation? Select all that apply.
3,000 = 50(60) + b
3,000 = 0.02(60) + b
60 = 50(3,000) + b
2,100 = 0.02(42) + b
2,100 = 50(42) + b
42 = 50(2,100) + b

Given a dilation with the origin O (0, 0), by observation determine the scale factor "K." DO, K = (5, 0) (10, 0) The dilation an
Julli [10]
A dilation is a transformation D_{o,\, k}, with center O and a scale factor of k that is not zero, that maps O to itself and any other point P to P'. The center O is a fixed point, P' is the image of P, points O, P and P' are on the same line.

In a dilation of D_{o,\, k} the scale factor, k is mapping the original figure to the image in such a way that the distances from O to the vertices of the image are k times the distances from O to the original figure. Also the size of the image are k times the size of the original figure.

Thus for a  dilation using the rule D_{o,\ k}=(5,\, 0)\rightarrow (10,\, 0) results in the distance of the image form O being twice the distance of the original point from O.

Therefore, it can be observed that the scale factor of the dilation, k, is 2.

Cleo wants to jion a gym. There is an initiation fee of $24.99, and each month of membership costs $12.50. If Cleo pays $174.99,
mamaluj [8]

Answer: The membership will last for 12 months.

Step-by-step explanation:

Let x represent the number of months that the membership would last.

Cleo wants to join a gym. There is an initiation fee of $24.99, and each month of membership costs $12.50. This means that the total cost of using the gym for x months would be expressed as

12.5x + 24.99

If Cleo pays $174.99, it means that

12.5x + 24.99 = 174.99

12.5x = 174.99 - 24.99

12.5x = 150

x = 150/12.5

x = 12

DanielleElmas [232]

Answer:

1. Let, Jamie needs "$ g" for the  trip. Then, according to the question,

g = 600 -------------------(1)

2. Let, Stella needs "$ m" for the trip. Then, according to the question,

m = 600 -------------(2)

3. If Jamie washes x no. of cars and Stella makes y no. of pies, then,

25x ≥ 600 ≥ 15y -------------(3)

4. Yes, Stella can afford to sign up for the trip with the money she earns.

Step-by-step explanation:

Let, Jamie needs "$ g" for the  trip. Then, according to the question,

g = 600 -------------------(1)

Let, Stella needs "$ m" for the trip. Then, according to the question,

m = 600 -------------(2)

if Jamie washes x no. of cars for $25 each and Stella makes y no. of pies

for $ 15 each, then, according to the question,

25x ≥ 600 ≥ 15y -------------(3)

Yes,  Stella can afford to sign up for the trip with the money she earns. Because, she can make at most 40 pies for $15 each and

$ 40 \times 15 = $ 600 = The amount of money Stella needs for the trip.
