Answer 4

Which of the following points lie in the solution set to the following system of inequalities?

y x - 5
y -x - 4

(1, 10)

(-1, 10)

(10, 1)

(1, -10)

Answer 5

First, you will need inequality signs in your inequalities

Answer 6

Then after you figure that out
You should just be able to plug in your choices and see which satisfy the system

Answer 7

You know see which is true

Answer 8

For example if we had the system of inequalities:
y<x-3
y>-x+5

And you wanted to see if (-4,3) was a solution to this system
You just plug it into both inequalities and if both inequalities hold true
then that point is an ordered pair that belongs to the solution set

So we have x=-4.y=3
Plug in -4 for x and 3 for y like this
3<-4-3
3<-7 not true
So we don't even need to check the other inequality to see if it is true or not

The order pair (-4,3) does not belong to system of inequalities I gave

Answer 9

which ordered pair does not satisfy the system 2x + y > 0 and -2x - y > -8?
