8x - 13y = 16
At the x intercept y = 0 so we have:-
8x - 13(0) = 16
8x = 16
x = 16/8 = 2
so the x intercept is at (2,0)
Applying multiplication of functions, the total number of seats in the auditorium is given by:
h(x) = 80x² + 560x.
<h3>How polynomial functions are multiplied?</h3>
They are multiplied applying the distributive property, that is, all the terms are multiplied and then the common terms are added.
In this problem, the functions are given as follows:
Then the multiplication is:
h(x) = f(x)g(x) = 80x(x + 7) = 80x² + 560x.
