0.85 * 100 = 85
Answer:
didn't get the question did u forget to put the sequence ???????
pls write the question fully so that I can help you
Work:
21x-7y=12
-7y=12-21x
y= -12/7+3x
Point: (1,-3)
y-y1=m (x-x1)
y+3= -12/7 (x-1)
y+3= -12/7x + 12/7
y= -12/7x -9/7
The equation is y= -12/7x- 9/7
Answer:
1 ≤ c ≤ 3
Step-by-step explanation:
In order to meet the standard, the chlorine level (c) must be at least 1 part per million (equal to or greater than 1):
1 ≤ c
At the same time, the level also needs to be no greater than 3 parts per million (equal to or lesser than 3)
c ≤ 3
Combining both inequalities yields (in parts per million):
1 ≤ c ≤ 3.
The compound inequality above describes the acceptable range for chlorine levels.
