a factory production is modeled by function f(x), where f(x) is the number of parts produced per hour and x is the number of people working during production. choose the ordered pair that represents a possible domain and rang of the function.

1. (-1, 15)
2. (5, -50)
3. (-10, -100)
4. (5, 10)

(5,10) because you can’t have a negative in people or in parts

Step-by-step explanation: We are given that a factory's production is modeled by function  f(x).

Where f(x)=Number of parts produced per hour

x=Number of people working during production

We have to choose an ordered pair that represents a possible domain and range of the function.

x is the number of people working during production.It is always positive because time can not be negative.

f(x) is the number of parts produced per hour .It is always positive because quantity of any number cannot be negative.It is always positive.

In first option (-1,15)

x=-1,f(x)=15

x is negative which is not possible.

So, it is false.

In option b(5,-50)

x=5,f(x)=-50

Range is negative which is not possible.

So , it is false.

In option C( -10,-100)

x=-10, f(x)=-100

x and f(x) are both negative  therefore, it is false.

In option D (5,10)

x=5 , f(x)=10

x and f(x) are both positive.

So, it is possible ordered pair.

Hence, ordered pair (5,10) in which 5  represent  a possible domain and 10 represent the possible range.

Good Luck :)

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
