ExtremeBDS [4]

The absolute value is defined as

|x|=\begin{cases}x&\text{if }x\ge0\\-x&\text{if }x

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

For the inequality |7 + 8<em>x</em>| > 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 + 8<em>x</em> ≥ 0, then |7 + 8<em>x</em>| = 7 + 8<em>x</em>, so that

|7+8x|>5\implies 7+8x>5 \implies 8x>-2 \implies x>-\dfrac14

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

|7+8x|>5\implies-(7+8x)>5\implies7+8x

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

yanalaym [24]

Answer:

first find the common factors of 18,26 and 72.

18: 1,2,3,6,9,18

26: 1,2,13,26

72: 1,2,3,4,6,8,12,18,24,36,72

next, find the common factors which can divide all numbers: 2

then find the highest factor which can divide all numbers. in this case, we only have one factor which is 2 and that shall be the H.C.F.
