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:

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)

What is the factored form of the expression. (2n^2 + 5n + 3) (4n - 5)
7nadin3 [17]

So firstly, <u>the factor (4n - 5) cannot be further factored, so we will be focusing on 2n² + 5n + 3.</u>

So for this, we will be factoring by grouping. Firstly, what two terms have a product of 6n² and a sum of 5n? That would be 2n and 3n. Replace 5n with 2n + 3n:

(2n^2 + 2n + 3n + 3)(4n - 5)

Next, factor 2n² + 2n and 3n + 3 separately. Make sure that they have the same quantity on the inside of the parentheses:

(2n(n+1)+3(n+1))(4n-5)

Now we can rewrite this expression as<u> (2n+3)(n+1)(4n-5) , which is your final answer.</u>

On a number line what is the difference between -3/7 and -2/3?
Yakvenalex [24]

Answer:  -5/21

Step-by-step explanation:

-3/7 & -4/6

common detonator is 42

-3/7 = -18/42 reduced to -9/21

-4/6 = -28/42 reduced to -14/21

difference between -9/21 and -14/21 = -5/21

If (a, -5) is a solution to the equation 3a = -2B - 7, what is a?
Andrew [12]
I think what you need to do is make B = -5
3a = -2(-5) - 7
3a = 10 - 7
3a = 3
a = 1

Suppose two $20 bills, three $10 bills, one $5 bill, and seven $1 bills are placed in a bag. If you were to pull a bill at rando
Korolek [52]

Answer:

Assuming that the $1 bill was pulled at random, then the expected value of the amount chosen is \frac{7}{13}.

Step-by-step explanation:

From the given question, the bag contains;

$1 bill = 7

$5 bill = 1

$10 bill = 3

$20 bill = 2

Total number of bills in the bag = 13

Pulling a bill at random, the bills would have an expected value as follows:

For $1 bill, the expected value = \frac{7}{13}

For $5 bill, expected value = \frac{1}{13}

For $10 bill, expected value = \frac{3}{13}

For $20 bill, the expected value = \frac{2}{13}

Assuming that the $1 bill was pulled at random, then the expected value of the amount chosen is \frac{7}{13}.
