Answer:
1. t > -6 (Graph A)
2. x ≤ −80 (Graph B)
3. b < 13 (Graph C)
Explanation:
1. t < 5t + 24
t − 5t < 5t + 24 − 5t
−4t < 24
−4t/−4 < 24/−4
t > −6
2. 5x−9≤4.1x−81
5x - 9 - 4.1x ≤ 4.1x - 81 - 4.1x
0/9x - 9 ≤ -81
0.9x - 9 +9 ≤ -81 + 9
0.9x ≤ -72
0.9/0.9 ≤ -72/-72
x ≤ -80
3. 4b+4(1-b)>b-9
so so and on
