Answer:

Step-by-step explanation:
x= 1 over 4y-2
domain is {2.4, 4.8, 6.3, 8.8, 10.1 }
For domain, equate f(x) to each value in the range and solve for x
7x - 2.7 = 14.1 ⇒ x =
= 2.4
7x - 2.7 = 30.9 ⇒ x =
= 4.8
7x - 2.7 = 41.4 ⇒ x =
= 6.3
7x - 2.7 = 58.9 ⇒ x =
= 8.8
7x - 2.7 = 68 ⇒ x =
= 10.1
the answer to the first part is 2x-3

Divides 45.85 by 15 you will get 3 same for the other cost- the divide 3 by 55.81 and you get 19
