The time length in hours of a certain airplane flight can be represented by the function f(x) = 0.0025x + 0.75, where x is the number of miles for the flight. The time length of another airplane flight in hours can be represented by the function g(x) = 0.004x + 0.5, where x is the number of miles for the flight. Which function represents the sum of the flight time lengths, h(x) = f(x) + g(x)?
h(x) = –0.029x + 0.25 ,h(x) = 0.0065x – 1.25 ,h(x) = 0.029x – 0.25 ,h(x) = 0.0065x + 1.25

Step-by-step explanation:

Given the time length in hours of a certain airplane flight represented by the function f(x) = 0.0025x + 0.75.

The time length of another airplane flight in hours can be represented by the function g(x) = 0.004x + 0.5.

x is the number of miles for the flight

The function that represents the sum of the flight time lengths is given as h(x) as shown;

h(x) = f(x) + g(x)

To get h(x), we will substitute the functions f(x) and g(x) into formula for function h(x) as shown below;

h(x) =  (0.0025x + 0.75)+(0.004x + 0.5)

Collecting the like terms;

h(x)= 0.0025x + 0.004x + 0.75 + 0.5

h(x) = 0.0065x+1.25

This gives the sum of the flight time lengths

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
