Question 77486: Hello out there,I had some problems that I need some help with badly,and thanks to whoever can help,the first question is,Determine if the equation is linear,and if it is put it in standard form.9y=4x-18.The next one is,xy=4.The next one is,x(with a 2 next it,I guess it means to the second power)-4=y.And the last problem is kinda hard,Two diced are rolled.Express a relation in a table for the possible numbers showing on the first die x and the second die y if the outcome is two odd numbers whose sum is a least 8.Thanks to whoever can help.

You can put this solution on YOUR website! the first question is,Determine if the equation is linear,and if it is put it in standard form.9y=4x-18.
It is linear because both x and y are to the 1st power
standard form is ax+by=c
For you 4x-9y=18 is the standard form
----------------
The next one is,xy=4.
This is not linear because the xy term is degree two.
--------------
The next one is,x(with a 2 next it,I guess it means to the second power)-4=y.
x^2-4=y
y=x^2-4
Not linear because the x is second power.

And the last problem is kinda hard,Two diced are rolled.Express a relation in a table for the possible numbers showing on the first die x and the second die y if the outcome is two odd numbers whose sum is at least 8.Thanks to whoever can help.
1 and anything will not add up to 8
2 and anything will not have two odd numbers
(3,5) works
4 and anything will not have two odd numbers
(5,3) works
6 and anything will not have two odd numbers
==========
