Answer:
a.
500x+0.04=y
400x+0.05=y
for percentages move decimal to the left twice
The discriminant is
which is 0.
Since the discriminant is 0, there is only one real solution.
get the equation in slope intercept form
2x-3y=9
subtract 2x from each side
-3y = -2x +9
divide by -3
y = 2/3 x -3
slope = 2/3
y intercept = -3
x intercept set y=0 and solve
0 = 2/3 x -3
add 3 to each side
3 = 2/3 x
multiply each side by 3/2
9/2 = x
the x intercept is 9/2 or 4 1/2
