It’s D bc Dt= 15x3 and it’s not that hard to solve
Alright, so the slope is alws in the middle so “u”
The answer is x=1 y=-1 and z=1. If you plug in the variables you get
4-3+5 and that equals 6. So that’s the answer
I believe none is the answer due to the fact it isn’t symmetrical. sorry if i am wrong. let me know if i am
Answer:
Option A : y = 40x - 85 is the correct answer.
Step-by-step explanation:
Given that:
Cost of purchasing supplies = $85
Cost charged for cleaning a pool = $40
Let,
x be the number of pools cleaned.
y be the profit
Profit = Cost of pools cleaned - purchase price of supplies
y = 40x - 85
Hence,
Option A : y = 40x - 85 is the correct answer.
