The function C(n) below relates the number of bushels of apples picked at a
pick-your-own orchard to the final cost for the apples.
It takes as input the number of bushels of apples picked after paying an entry
fee to an orchard and returns as output the cost of the apples (in dollars).
(n) = 10n + 20
Which equation below represents the inverse function N(C), which takes the
cost of the apples as input and returns the number of bushels picked as
output?
A. N(C)=570
B. N(C) =
C +10
20
C. N(C) = C-20
10
D. NCC)=120

answer: sorry

step-by-step explanation: can you tell me pls how to find the rational of two integers

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
