Answer:
Explanation:
To find the function that represents the total flight times, we need to add the functions f(x) and g(x) together:
f(x) = 0.003x - 1.2
g(x) = 0.0015x + 0.8
Adding these two functions, we get:
h(x) = f(x) + g(x)
= (0.003x - 1.2) + (0.0015x + 0.8)
Simplifying the expression:
h(x) = 0.003x - 1.2 + 0.0015x + 0.8
= (0.003x + 0.0015x) + (-1.2 + 0.8)
= 0.0045x - 0.4
Therefore, the function that represents the total flight times is:
h(x) = 0.0045x - 0.4
