Math Problem Statement

∣x−4∣>8

Solution

The inequality x4>8|x - 4| > 8 means that the absolute difference between xx and 4 is greater than 8. To solve this inequality, we need to consider the definition of absolute value, which gives us two possible cases:

Case 1: x4>8x - 4 > 8

Solve for xx: x4>8x - 4 > 8 x>12x > 12

Case 2: x4<8x - 4 < -8

Solve for xx: x4<8x - 4 < -8 x<4x < -4

Final Solution:

Combining both cases, the solution to the inequality is: x>12orx<4x > 12 \quad \text{or} \quad x < -4 In interval notation, the solution is: (,4)(12,)(-\infty, -4) \cup (12, \infty)
