Question

PLEASE I SERIOUSLY NEED HELPP (ill be ur best friend if u answer these I promise. just please do this for me)

solve the inequalities
|2x+2|<25
|d+2|≥6
4|x+1/3|=20
|x|-7=6
-2|h-7|=-28
|3x+6|<12
|2k+1|≥5

Answer 1

(−27/2) < x < (23/2)

d ≤ −8 or d ≥ 4

x = (14/3), (−16/3)

x = 13,−13

h = 21, −7

−6 < x < 2

k ≤ −3 or k ≥ 2

Explanation:

|2x + 2| < 25

(−27/2) < x < (23/2)

|d + 2| ≥ 6

d ≤ −8 or d ≥ 4

4|x + 1/3| = 20

x = (14/3), (−16/3)

|x| - 7 = 6

x = 13,−13

-2|h -7| = -28

h = 21, −7

|3x + 6| < 12

−6 < x < 2

|2k + 1| ≥ 5

k ≤ −3 or k ≥ 2
