I do not know the answer to this question
Answer:
(g + f)(x)
Step-by-step explanation:
the outputs of f(x) and g(x) will always have a sum of -1, which is h(x).
<span>Systems of equations:
x = number of adult tickets sold
y = number of student tickets sold
x + y = 396
y = 2x
if y = 2x that means we can literally put 2x in for y in the first equation.
x + (2x) = 396
3x = 396
x = 132
x + y = 396
132 + y = 396
y = 264</span>
