Question

rend 11) -5b-83-68 or llb - 12

Answer 1

-5b - 8≤ - 68

then

-5b ≤ -60

b ≤ 60/5

b ≤ 12

also

11b - 12 < -100

then

11b < -88

b < -88/11

b < -8

Now graph inequality

Q12

36 ≤ 11 - 5x

then

36-11 ≤ -5x

25 ≤ -5x

25/-5 ≤ x

-5 ≤ x

also

11 - 5x ≤ 66

then

-5x ≤ 66 - 11

x ≤ (66 - 11) /-5

x ≤ 55/-5

x ≤ -11

Then answer is

- 11 ≥ x ≥ -5
