Question

Which of these ordered pairs is a solution to the inequality
3x + y > – 8 ?

Answer 1

answers could be
(–3, 0)
(–2, –1)
(0, –10)
(2, –16)

Answer 2

try subbing in your answer choices...
let me do the first one
3x + y > -8
(-3,0) x = -3 and y = 0
now sub
3(-3) + 0 > - 8
-9 + 0 > -8 (not correct)

first one is not correct, you want to try the 2nd answer choice ?

Answer 3

sure

Answer 4

3(-2) + -1 = -7

Answer 5

Answer 17

@holly43 .....I answered your message

Answer 18

@kelliegirl33

Answer 20

we do this one just like the last one...by subbing
y - 2x <= -3

(2,4)
4 - 2(2) <= -3
4 - 4 <= -3
0 <= -3 (not this one)

(-2,3)
3 - 2(-2) <= -3
3 + 4 <= -3
7 <= -3 (nope)

(3,4)
4 - 2(3) <= -3
4 - 6 <= -3
-2 <= -3 (nope)

(1,-1)
-1 -2(1) <= -3
-1 - 2 <= -3
-3 <= -3 (BINGO...it would have to be the last one..lol )
