Let n =  the hours elapsed when the two trains are 660 miles apart.


Let the first train travel east and the second train travel west.

The distance traveled by the first train is

x = (50 mi/h)*(n h) = 50n mi


The distance traveled by the second train is

y = (60 mi/h)*(n h) = 60n h


The distance between the two trains after n hours is

x + y = 50 n + 60n = 110n mi


Because this distance is 660 miles, therefore

110n = 660

n = 6 hours


Answer: 6 hours


I hope this helps. Sorry it took so long

Can someone please help me please?
ladessa [460]

Answer:

B

Step-by-step explanation:

F(x) is just a negative vertical shift downwards, so when you have a downwards shift the number of units down is placed right after the x outside of the parenthesis. In this case, there was a shift of -4, so it would be -x^2 - 4.

Part 1 -

1. f(x) = 5(x-2)^2 + 4

axis of symmetry: x = 2

vertex: (2, 4)

2. f(x) = 12(x + 6)^2 - 5

axis of symmetry: x = -6

vertex:  (-6, -5)

3. f(x) = 2x^2 + 8x - 7

axis of symmetry: x = -2

vertex: (-2, -15)

I have to go somewhere right now, but I will get back to you as soon as I can (probably within a couple of hours) to finish answering the rest of your questions.
