what is x+y<1?

Answer 1

There needs to be a second equation. Right now, it's a binomial inequality.

Answer 2

It's a whole load of solutions...

x=0, y=0
x=0.5, y=0.3
x=4, y=-3.5

It's an 'inequality'. Any pair of numbers for x and y which add up to **less than** one, are valid.

You can graph this. Draw the line for which x+y = 1 (it's a \ line passing through x=1 and y=1). This separates the graph into three parts: the bottom left is x + y < 1, the top right is x+y > 1, and all points on the line are x+y = 1. Any point in the bottom right section is a valid answer.

Points on the line, however, are NOT valid answers. If the equation was x + y <= 1 (usually written with < with a line under it), then the points on the line would be, as well.

Answer 3

x=-1 y=1
-1+1=0<1

Answer 4

x=0 y=0

Answer 5

it's a linear inequality.

the value of y depends on the value of x, and it's the same the other way.

for example, in x+y<1, if the value of x is 0, then 0+y<1, then y<1. which means that the value of y can be anything less than 1.

Answer 6

You haven't got enough information to actually get a value for either x or y. There are infinite ways you could fill in for x or y and still have a true equation.

Answer 7

It is an inequality.
It limits the combined values of x and y
but does not limit the value of either.

Answer 8

nothing. you know that x and y both have to be less than 1

Answer 9

It's a mathematical expression

Answer 10

anything you want it to be. an infinite amount of solutions.
