Answer:
45
Step-by-step explanation:
5 less than your number is at least 40. Let the number be x. So rephrasing the statement, 5 less than x is greater than or equals 40.
x-5 ≥ 40
x-5+ 5 ≥ 40+5 (adding 5 to both sides to single out the x in LHS)
∴x ≥ 45
In other words, x is at least 45.
Therefore, the minimum value of x is 45.
Answer:
A, B, D
Step-by-step explanation:
A is true. From week 5 to week 11, the curve goes down.
B is true. After week 11, the curve goes up.
C is false. The curve passes $320 twice in the first ten weeks, not three times.
D is true. The curve starts at about $110.
E is false. As time increases, the graph goes up. As time decreases, the graph goes down.
Answer:
Values that make 4p - p < 13 true are {1,2,3, and 4}, and values that make 4p - p >13 true are {5,6,7,8, and 9}.
Step-by-step explanation:
Solve the first inequality.
4p - p < 13
3p < 13
p < 13/3
Any values less than 13/3.
Then solve the second inequality.
4p - p > 13
p > 13/3
Any values greater than 13/3.
