Why am i on this app i am so dumb
563/.4 is equal to 1,407.5
Let
x--------> the time in hours
y-------> the distance in miles
we know that
The speed is equal to
in this problem
<u>Equation First Train</u>
<u>Equation Second Train</u>
---------> equation 
Substitute the values of 
and 
in the equation
Solve for x
therefore
<u>the answer is</u>
F(x) = 16^x = 8^2x
g(x) = 16^1/2x = 8^x
So you can see the relationship. They are all of the type a^bx form, with same base of a, f(x) will have larger increasing rate.
To solve:
-2x = 34
----- -----
-2 -2
(-2x means -2 times x, so to undo this we need to divide by -2 on both sides)
x = -17
Then you do basic division (knowing that a positive divided by a negative results in a negative answer). And that's it!
