ERRE A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
O(x, y) - (x + 5, y-3)
(x, y) - (x + 5, y + 3)
O (x, y) - (x-3, y + 5)
O(x, y) - (x + 3, y + 5)

"translated 5 units up" means y becomes y+5. We just add 5 to whatever the y coordinate is to shift the point 5 units up.

To shift 3 units left, we subtract 3 from whatever the x coordinate value is. So we go from x to x-3.

Put this together and the translation rule is

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
