Question

please answer me fast ​

Answer 1

Answer:

1-- x can be any no. as we take -2 as x so 5*(-2) = -10-3=-13

and

3*(-2) = -6+1= -5

2--x is still an integer as it's small than 0 so

{-3(or any integer .) -1} square {-3+1}cube and (-3-4)

so - 8 * (-26) * (-7) = -

• wavy curve method
• property of modulas function

$\\ \green{ \mathrm{solution}} \: \\ \\ \\ answer(1)$

$\longrightarrow 5x-3<3x+1 </p><p> \\ \longrightarrow5x-3x<1+4 \\ \longrightarrow2x<4 \: \\</p><p> \longrightarrow \: x < 2 \\ \longrightarrow x - 2<0$

use wavy curve method

critical points is 2

so

$\\ x \in( - \infty\: , 2 \: ] \:\:$

$\\ answer(2)$

use wavy curve method critical points are

1,-1, 4 ( see attachment 2 )

$\\ x \in( - \infty \: , \: - 1 ] \: \cup \: [ \: 1, 4 \: ] \:$

$\\ \\ answer(3)$

$\longrightarrow \: |2x - 3| = 4 \\ \longrightarrow \: 2x - 3 = \pm4 \\ \longrightarrow \: 2x - 3 = - 4 \: \: \: .......1\\ \longrightarrow \: 2x - 3 = + 4 \: .........2$

on solving these two equations

we get

$\\ x \: = \: \frac{7}{2} \\ \\ x \: = \: \frac{ - 1}{ \: \: 2}$
