Answer:
|x + 7| ≥ 2 is the inequality
Step-by-step explanation:
x - b ≥ c or x - b ≤ -c
x ≥ b + c = -5 or x ≤ b - c = -9
b + c = -5
<u> b - c = -9</u>
2b = -14
b = -7 -7 + c = -5
c = 2
x - (-7) = x + 7
So, |x + 7| ≥ 2 is the inequality
60t+20t=150
80t=150
t=150/80=15/8
Note: t is only half the time, the total time is 15/4=3 hours 45 minutes
Answer:
Between 7 and 8
Step-by-step explanation:
6^2 = 36
7^2 = 49
8^2 = 64
9^2 = 81
since 61 is between 7^2 and 8^2, √61 is between 7 and 8
