Please help me. Medals awarded
which ordered pair is a solution to the system?
system: y > -2
x + y < 4

A. (-3,5)
B. (0,4)
C. (-2,-3)
D.(1,4)

Answer 1

Take each choice and see which works;

For example, choice (A)... x = -3 and y =5..does this work for both inequalities? Well, y > -5 which is good as we have y = 5; and is -3+5<4, yes it is..so A is a solution.

Check that the other pais do NOT work for both inequalities.

Answer 2

start plugging in each point and check whether both inequality satisfies.
i'll do the last one, you do the 1st, deal ?
1,4 -----> x=1, y=4

y>-2
4>-2 ---> TRUE

x+y<4
1+4<4
5<4 --->FALSE

so last option is not correct.
got this ?

Answer 3

hartnn answer is good!

Answer 4

(-3,5)
5 > -2 true
-3 + -2 = -1
-1< 4 trueee

Answer 5

good work! :)

Answer 6

thanks so much 1 :)

Answer 7

welcome so much 1 :)

Answer 8

but actually
x+y = =3+5 = 2
and 2<4 is trueee
