I've tried solving this inequality multiple times and I just can't get it right. I don't know what I'm doing wrong. please help

The absolute value is defined as

So for example, if x = 3, then |x| = |3| = 3, since 3 is positive. On the other hand, if x = -5, then |x| = |-5| = -(-5) = 5, since -5 is negative. The absolute value is always positive.

For the inequality |7 + 8x| > 5, you consider the two cases where the argument to the absolute value (the expression you find inside the bars) is either positive or negative.

• If 7 + 8x ≥ 0, then |7 + 8x| = 7 + 8x, so that

• Otherwise, if 7 + 8x < 0, then |7 + 8x| = -(7 + 8x), so that

The solution to the inequality is the union of these two intervals.

hey i’m new i won’t be answering any questions now bye peeps see you next time

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
