Determine if JK and LM are parallel, perpendicular, or neither in the following questions. 1) J(1,9), K(7,4), L(8,13), M (-2, 1)

2) J(13, -5), K(2, 6), L(-1, -5), M(-4, -2)

3) J(-10, -7), K(-4,1), L(-3, 2), M(-6, -2)

4) J(11 -2), K(3, -2), L(1, -7), M(1, -2),

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
