So the longer lines are 2x longer than the shorter lines
Look at line segment BD
40 is 2x as long as 9x+2
In order to make the equation true, multiple 9x+2 by 2
So, you should get:
40=18x+4
36=18x
x=2
Plug the 2 into 19X+14, and divide that answer by 2, because GF is 2x smaller than AG
19x+14
19(2)+14
52
52/2=26
Hope this helps!!
Visualize one train going north and the other going south. To determine their distance apart, we could add the distance one train travels north to the distance that the other train travels south.
Thus, |62 kph * t| + |68 kph * t] = 455 km (Seems that you may be mixing km with miles; can't do that; choose one or the other.)
Then
455 km
------------------------ = t = 3.5 hours
(62 kph + 68 kph)

Given:
f(x) is an exponential function where f(3) = 18 and f(7.5) = 60.
To find:
The value of f(12), to the nearest hundredth.
Solution:
Let the exponential function be
...(i)
It is given that . Substitute in (i).
...(ii)
It is given that . Substitute in (i).
...(iii)
Divide (iii) by (ii).
Putting in (ii), we get
Putting and in (i), we get
Putting x=12, we get
Therefore, the value of f(12) is about 200.00.
