Answer:
A. 132 + 22h > 264
Step-by-step explanation:
Hourly sales = 22 glasses of fruit punch
Sales by 4 p.m = 132 glasses
Goal = more than 264 glasses
h = number of hours they must stay open to make their goal
The inequality:
132 + 22h > 264
22h > 264 - 132
22h > 132
h > 132/22
h > 6 hours
This means, the number of hours they must stay open to make their goal of more than 264 glasses is more than 6 hours
You multiply the slope with the points
Answer: 15-9a+b+3c
Step-by-step explanation:
~ 2a-4c = 20-3a+b-4c = 20-4a+2b+3c = -15
~ 20-5a+b=20-4a+2b+3c=-15
~ -9a+b+3c = -15
~ 15-9a+b+3c
