Решите неравенства плеаз 7x+7<3x -3x-1>-8x -8x+6>-9x 9x-7>x 8x-1>4x -7x-10>-3x -3x+6>5x -8x-1>2x -4x-6≤-7x

Answer 1

1) 7x +7 <3x</p>

4x < -7

x < -7/4

2) -3x -1 > -8x

5x > 1

x > 0.2

3) -8x +6 > -9x

x > -6

4) 9x -7 > x

8x > -7

x > -7/8

5) 8x-1>4x

4x > 1

x > 0.25

6) -7x-10>-3x

-4x > 10

x < -10/4

7) -3x+6>5x

-8x > -6

x < 6/8

8) -8x -1 > 2x

-6x > 1

x < -1/6

9) -4x-6  <= -7</p>

-4x <= -1</p>

x >= 0.25
