9<= (11x-18)/9 <20

9 \leq \frac{11 x - 18}{9} < 20

9 \leq x < 18

Interval Notation

[9, 18)

Solution steps

9 \leq \frac{11 x - 18}{9} < 20

a \leq u < b

then

a \leq u and u < b

9 \leq \frac{11 x - 18}{9} and \frac{11 x - 18}{9} < 20

9 \leq \frac{11 x - 18}{9} : x \geq 9

\frac{11 x - 18}{9} < 20 : x < 18

Combine the intervals

x \geq 9 and x < 18

Merge Overlapping Intervals

9 \leq x < 18

(- 5)^{2}

\frac{d}{d t} (\frac{( i + 2 t )}{( t - i )})

x^{3} + 5 x^{2} + 6 x

5 x^{3} + x^{2} - 45 x - 9

20 = 6 + 38 t - 16 t^{2}
