4.6 because the square root of 16 is 4 and the square root of 25 is 5 so 4 would be closest
Answer:
9
Step-by-step explanation:
Firstly you can simplify the exponents shown below:

Simply add exponents when multiplying like shown above.
Part A: Yes there is. As the number of workers increases, so does the production.
Part B: y = 5x + 2
Part C: The slope indicates that for every person there is 5 units being produced, and the y-intercept indicates that 2 units are being made every day, regardless of if there are no workers ( this, however is unrealistic but it is how the data is )
Its the first one
Plugging in x = -2 and y = -1:-
5(-2) = -10
11(-2) - (9)-1) = -22 + 9 = -13
