Pregunta 20 (1 punto)Guardado¿Cuál de los siguientes pares ordenados (x,y) no es parte del conjunto solución a ladesigualdad 3x<15-y?(6,3)(3,6)O 1 (-3, 6)O(-6,3)

Answer 1

Option C and D are correct.

(-3, 6) and (-6, 3) satisfy this inequality expression.

Step-by-step explanation

3x < 15 - y

Trying the options one at a time with the order (x, y)

(6, 3)

x = 6, y = 3

3x < 15 - y

3(6) < 15 - 3

18 < 12

This is not true, so, this option isn't correct.

(3, 6)

x = 3, y = 6

3x < 15 - y

3(3) < 15 - 6

9 < 9

This is not true too. This option isn't correct too.

(-3, 6)

x = -3, y = 6

3x < 15 - y

3(-3) < 15 - 6

-9 < 9

This is true. Hence, this option is correct.

(-6, 3)

x = -6, y = 3

3x < 15 - y

3(-6) < 15 - 3

-18 < 12

This is true. This option is correct too.

Hope this Helps!!!
