Question

which point is a solution to the following inequalities? x-2y>10 3x+4y <10

Answer 1

(1, 10)
(2,-3)
(4,-4)
(-2,-5)


Could someone explain?

Answer 2

There's two ways to do it. The Easy Way is:
Plug in the values of x,y in each point into one of the inequalities, until you find the correct one.

Answer 3

The Longer Way: Solve one of the inequalities for x or y, then plug it back into the other inequality, then solve.
i.e x-2y>10 would be x>2y+10 when solved for X.
Then plug that for X into the other inequality.
3(2y+10)+4y<10. Then solve for Y

Answer 4

Oh, I see. Thanks!

Answer 5

No problem.
