Determine if the equations represent lines that are parallel, perpendicular, or neither.

lines are parallel and m = 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

14x = 2y - 6 or

2y - 6 = 14x ( add 6 to both sides )

2y = 14x + 6 ( divide through by 2 )

y = 7x + 3 ← in slope- intercept form

with slope m = 7

------------------------------

= y - 7x or

y - 7x = ( add 7x to both sides )

y = 7x + ← in slope- intercept form

with slope m = 7

Since slopes of both lines are equal, both m = 7 then lines are parallel

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
