Answer:
Pete's:
Carla's:
Step-by-step explanation:
Let's assume that is the amount of rooms painted, and
For Pete's Painting Company, they charge a flat fee of $60, so we will have a constant of 60.
They also charge 20$ per room, meaning that we will multiply 20 by , the amount of rooms painted.
This gets us the function
For Carla's Creative Colors, they charge 20$ to hire the workers, meaning this will be our constant.
They also charge $40 a room, meaning we will multiply 40 by , the amount of rooms painted.
So the function is .
Hope this helped!
Since the ratio of mother to daughter is 4:1, the weight of the mother and daughter together is five times the weight of the daughter.
In fact, if the daughter weights pound, the mother weights
pounds, and the total weight is
.
We know that this total is 185 pounds, so we have
So, the daughter weights 37 pounds.
Option C: is the equation that have a greater rate of change.
Explanation:
From the graph the coordinates are (0,0), (20,6), (40,12), (60,18) and (100,30)
We need to determine the rate of change.
The rate of change can be determined using the formula,
Substituting the any two coordinates in the formula, we get, the slope of the equation.
Let us substitute the coordinates (20,6) and (100,30)
Thus, we have,
Simplifying, we get,
Dividing, we get,
Also, the y - intercept of the equation is
The equation of the line becomes
Thus, the equation that has a greater rate of change is
Hence, Option C is the correct answer.
