The answer to the question is B
Answer: Answer: (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 :)
Answer:
1) +1,+2,+3,+6,-1,-2,-3,-6
2) f(2) = 0
3) (x+1)(x-2)(x-3)
4) x=-1, x=2, x=3
Step-by-step explanation:
For explanation, see the attached files
The answer would be C. 8.
I would cross multiple the fractions (3*40) and (15 * x)
That would equal 15x= 120
Divide both sides by 15 and you get 8
Or
You could say: what number times 3 gives me 15? The answer would be 5 and then you would divide 40 by 5 to get 8.
Hope the explanation helps :)
