6. Suppose y varies directly as x, and y = 16 when x = 8. Find y when x = 16.

y=32

Step-by-step explanation:

Basically, the equation is saying that every x=2y

Based on this we can conclude that when x=16, we have to multiply y by 2 to find out what y equals.

16x2=32

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130

f(x)=2/3x-8, which give g(x) the greatest value.
