The fireworks will launch from a boat in the bay, and must land in a designated "fire safe" zone 100 meters away. to be visible above the buildings and the trees, the fireworks must reach at least 30 meters high. write an equation that could model the path of the fireworks.

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

welcome!

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
