The annual yield per lemon tree is fairly constant at 390 pounds per tree when the number of trees per acre is 150 or fewer. For each additional tree over ​, the annual yield per tree for all trees on the acre decreases by 4 pounds due to overcrowding. A. Express the yield per​ tree, Y, in​ pounds, as a function of the number of lemon trees per​ acre, x, where x is greater than 150.
B. Express the total yield for an​ acre, T, in​ pounds, as a function of the number of lemon trees per​ acre, x, where x is greater than 150.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)

thus, the first answer choice, y = sec x, is the correct one
