Becky and Cathy are sisters . Becky is four year older than Cathy . The following shows how Becky ages y changes as Cathy age is x changes

D. y=x+4

Step-by-step explanation:

The y value in this graph is the x value + 4, such as the points (0,4) and (2,6) that lie on the graph. You can also tell by the y intercept being 4 on the graph and the slope being one.

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
