The number of rows in an auditorium can be represented by the function f(x) = 80x. The number of seats in each row can be represented by the function g(x) = x + 7. Which function represents the total number of seats, h(x) = f(x)g(x)? h(x) = 136x h(x) = 80x2 + 560x h(x) = 80x + 560 h(x) = 80x2 + 560

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

answer: the answer is d

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
