If (-1, y) lies on the graph of y = 3x+1, then y =

0
1/3
1

y = -2

Step-by-step explanation:

We have a point (-1,y) on the graph of y = 3x + 1

When x = -1 then,

y = 3(-1) + 1

y = -3 + 1 = -2

b. t=-25h+3

step-by-step explanation:

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
