Question

Ariana correctly simplify an expression. When she substituted x equals 2 into the simplify expression, the value was -4 which could be Ariana's original expression
1/6(-3x-24)

1/6(-5x-8)

1/6(-10x-4)

1/6(-12x-16)

Answer 1

The correct answer would be C. Hope it helps :)

Answer 2

Answer:

Ariana's original expression  is

$\dfrac{1}{6}\times (-10x-4)$

Step-by-step explanation:

• $\dfrac{1}{6}\times (-3x-24)\\\\at\ x=2,\ we\ get\\\\\dfrac{1}{6}\times (-30)\\ \\=-5$

• $\dfrac{1}{6}\times (-5x-8)\\\\at\ x=2,\ we\ get\\\\\dfrac{1}{6}\times (-18)\\ \\=-3$

• $\dfrac{1}{6}\times (-10x-4)\\\\at\ x=2,\ we\ get\\\\\dfrac{1}{6}\times (-24)\\ \\=-4$

• $\dfrac{1}{6}\times (-12x-16)\\\\at\ x=2,\ we\ get\\\\\dfrac{1}{6}\times (-40)\\ \\=-20/3$

Hence, Ariana's original expression  is

$\dfrac{1}{6}\times (-10x-4)$
