Question

HURRY PLS The length of time in hours of two airplane flights are represented by the following functions, where x is the number of miles for the flight:
Flight A: f(x) = 0.003x – 1.2

Flight B: g(x) = 0.0015x + 0.8

Which function represents the total of the flight times, h(x) = f(x) + g(x)?

h(x) = 0.0015x – 2
h(x) = 0.045x – 0.4
h(x) = 0.0045x – 0.4
h(x) = 0.0045x – 2

Answer 1

Answer:

h(x) = 0.0045x – 0.4

Step-by-step explanation:

The length of time in hours of two airplane flights are represented by the following functions, where x is the number of miles for the flight.

Flight A: f(x) = 0.003x - 1.2

Flight B: g(x) = 0.0015x + 0.8

Then the function  

h(x) = f(x) + g(x) = (0.003 + 0.0015)x + (-1.2 + 0.8) = 0.0045x - 0.4.

Therefore, the third option is the right option. (Answer)
