Dafna1 [17]
Lynne will charge $20.75 to walk each of the 8 dogs. You see, there is a constant pattern of $2.75 between each dog as the number of them gets higher and higher

For example:

40.00-37.25= 2.75
37.25- 34.50=2.75

To get this answer, you just had to keep subtracting 2.75 until you got to 8 dogs. Hope this helps! Have a blessed day!!

A function is created to represent the miles per gallon your car gets. What restrictions would be made to the domain?. a. The do
Ahat [919]

Answer: d. The domain would only include positive numbers.

Step-by-step explanation:

Given: A function is created to represent the miles per gallon your car gets.

Here, the independent variable = the amount of fuel the car gets in gallons.

and the dependent variable = the total miles of car travel .

We know that the domain of a function is a set of all values of independent variable.

Thus, the domain would only include positive numbers because the quantity of fuel in a car is never negative and it can be in fraction .

Hence, D is the right answer.

Which graph shows a set of ordered pairs that represents a function?
pychu [463]

Answer:

B represents a function.

Step-by-step explanation:

Recall these characteristics of a "function:"

Only one y-value can be associated with each x-value.  

Thus, A could not represent a function because there are two points with x = 1 and two different y-values:  (1, 1) and (1, -2).  

B represents a function because for each input (x-value) there is one and only one y-value associated.

C not a function:  (2, 3) and (2, -3) have two different y-values associated with one x-value (2).

D not a function:  (-3, 4) and (-3, -4) (see A and C, above)
