What is the inverse of the function below?
f(x)=2x+12/5
a.) f^-1(x)=5/2x+12
b.) f^-1(x)=5/2x-6
c.) f^-1(x)=-2x-12/5
d.) f^-1(x)=14/5x

Option B is the correct answer.

Step-by-step explanation:

Finding inverse,

Option B is the correct answer.          

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
