Answer: A
5.64-4.44 = 1.20
6.84-5.64 = 1.20
8.04-6.04 = 1.20
Each additional two hours adds $1.20 to the rental, so a slope of $0.60 per hour. That's the incremental cost per hour.
Two hours costs $4.44 so zero hours costs 4.44-1.20=$3.24. That's the y intercept, representing a fixed fee for every rental.
4(a-9)=-30
Hope this helps!
Answer: k ≥ 50
Step-by-step explanation:
From the question, we are informed that Derek will get a bonus if he sells at least 50 sets of knives in a month. We are further told to us k to represent the number of knives he can sell to receive his bonus.
Since we are told that Derek will get a bonus if he sells at least 50 sets of knives in a month, this means that k will be greater than or equal to 50. Therefore,
k ≥ 50

thats what i did to get -469. show your work for finding -109 and we can compare
