Answer: 
Step-by-step explanation:
Step 1:-
Given equations are y=-2 x+30........(1)
another equation is y=4 x ..........(2)
Step 2:-
solving these two equations (1) and (2)
Equating both equations are 


Step 3:-
The final answer is 
X+ 4? idk I don't really understand the question...

Answer: x = 1/6 or x = 0.1666666666666...
Hope this helps!
If your functions are
f(x) = 16·x
g(x) = 16·(1/2x)
The output values of g(x) are one-half the output values of f(x) for the same value of x.
If your functions are
f(x) = 16^x
g(x) = 16^(1/2x)
The output vaules of g(x) are the square root of the output values of f(x) for the same value of x.
