Do you want me to divide that? I will answer in comments if so.
The answer is D.
The domain represents the total number of flowers produced in 11 months.
Y=-x-2 that is how you graph it
x=12.3
Combine the like terms (add the constants together and add the variables together)
The sum of the variables is 19x and the sum of the constants is -54
Add 54 to 180 and you'll get 234
Divide 234 by 19
The quotient is 12.31579
Round that to the nearest tenth and 12.3 is your answer
I don't know about the first one but for the second one:
