x equals 6x=6,

and

x equals negative 6x=−6.

B.

f has a zero of the denominator at

x equals 6x=6.

C.

There are no zeros of the denominator.

D.

f has zeros of the denominator at

x equals 12x=12

and

x equals 6x=6.

false.

step-by-step explanation:

false.

cavalieri's principle makes that statement about the volumes, not about the areas.

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
