TOLONG DIJAWAB YAAA

Answer 1

A. 4(3 - 2y) ≤ - 12
12 - 8y ≤ -12
24 ≤8y
3 ≤ y

b. 2(3p - 4) - 8p ≥ 0
6p - 8 - 8p ≥ 0
-2 p - 8 ≥ 0
-8 ≥ 2p
-4 ≥ p

c. 4 - 3n/5 ≥1/2
7/2 ≥ 3n/5
7/2 : 3/5 ≥ n
35 / 6 ≥ n

d. 1  - 2m/5 ≤ 3
-2 ≤ 2m/5
-10 / 2 ≤ m
-5 ≤ m

e. 7k +  3 ≥ 4k -2
7k - 4k ≥ -2 - 3
3k ≥ -5
k ≥ - 5/3
