Answer:
x=0
Step-by-step explanation:
Setting f(x)= (x-4)(x+4) = to 0 and solving for x produces the two x-intercepts (not Intersepts) of the function: They are 4 and -4.
The midpoint between these two intercepts is 0.
For this case, the first thing we must do is define variables.
We have then:
x: number of $ 10 coins
y: number of $ 20 coins
We now write the system of equations that models the problem:


The graphical solution (see attached image) is given by the intersection of the equations.
We have then:


Answer:
