3) What are the x intercepts?
4) What are the y-intercepts?
5) What are the coordinates of the Maximum?
Is there a Minimum?
6) State the intervals over the x-axis inwhich the graph is increasing,
7) State the intervals over the x-axis inwhich the graph is Decreasing
8) State the intervals over the x-axis inwhich the graph is Positive.
9) State the intervals over the x-axis inwhich the graph is Negative.

replication and blocking

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
