Choose the graph of the inequality's solution. -4x + 8 > 12

alexandr402 [8]

Answer:

$x < - 1$

You should have a circle on -1 with the arrow going left

Step-by-step explanation:

Subtract 8 from both sides.

$- 4x + 8 > 12 \\ - 8 \: \: \: \: - 8$

$- 4x > 4$

Divide by -4

$\frac{ - 4x}{ - 4} > \frac{4}{ - 4}$

Since you are dividing by a negative, you need to flip the inequality.

$x < - 1$
