Question

1)-у>5 2)-у <= -3 3)-у<1/7 4) -у>= 6,1 5)1-2у>= 16 6)29>у-27​

Answer 1

Ответ:

1) -y>5

-1x(-y) <-1×5

y<-1×5

y<-5

3) -y<1/7

-1x(-y) >-1×1/7

y>-1×1/7

y>-1/7

6) 29>y-27

-y+29>-27

-y>-27-29

-y>-56

y<-56

Answer 2

To solve the inequalities, let's analyze each one individually:

1. -у > 5:

To isolate у, we flip the inequality sign and multiply both sides by -1: у < -5

2. -у <= -3:

To isolate у, we flip the inequality sign: у >= 3

3. -у < 1/7:

To isolate у, we flip the inequality sign and multiply both sides by -1: у > -1/7

4. -у >= 6.1:

To isolate у, we flip the inequality sign and multiply both sides by -1: у <= -6.1

5. 1 - 2у >= 16:

First, we subtract 1 from both sides: -2у >= 15

Next, we divide both sides by -2, remembering to flip the inequality sign since we're dividing by a negative number: у <= -7.5

6. 29 > у - 27:

First, we add 27 to both sides: 56 > у

So, combining all the results, we have:

у < -5 у >= 3 у > -1/7 у <= -6.1 у <= -7.5 56 > у
