Are these two problems proportional or non-proportional? Why or why not? Explain your reasoning below. y=3/4x
y=1/2x-6

Given:

To find:

Whether the above functions are proportional or non-proportional?

Solution:

If y is proportional to x, then

where, k is constant of proportionality.

The proportional relationships are in the form of   and they passes through (0,0).

Putting x=0 and y=0 in the given equations.

It is a true statement.

It is a false statement.

Therefore, is proportional and is non-proportional.

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!

ian gonna lie that is way to much
