+1

Solution steps

9 ∣ y - 8 ∣ - 6 \geq 30

Move

6

to the right side

9 ∣ y - 8 ∣ \geq 36

Divide both sides by

9

∣ y - 8 ∣ \geq 4

Apply absolute rule: If

∣ u ∣ \geq a, a > 0

then

u \leq - a

|(-2x+9)(x-1)|<5|x-1|

∣ (- 2 x + 9) (x - 1) ∣ < 5 ∣ x - 1 ∣

∣ x - 3 ∣ - ∣ x - 6 ∣ > 1

∣ 4 x - 1 ∣ + 4 > 0

(x^2-4|x|+3)/(x(x+4))=>0

\frac{x ^{2} - 4 ∣ x ∣ + 3}{x ( x + 4 )} => 0

∣ x - 3 ∣ + 2 ∣ x + 1 ∣ > 4
