You have a line:
y=mx+b (slope-intercepted form)
m=slope of this line.
The slope of a line perpendicular to that given line will be: ´"m´"
m´=-1/m.
For example:
y=8x+3
m=8
The solpe fo a line perpendicular to "y=8x+3" is:
m`=-1/8
I f you divide 350 by 2 you get 175. Then take 175 and multiply it by 6 you get 1,050 liters.
Answer:

n ≈ 3
Step-by-step explanation:
9n-2<7+20

The answer is 4 because the portion labelled J shows a constant function but is not at the starting point
Ms Mess gave 2*100=200$
The Clerk gave 3*50=150$
200-150=50$
The end up paying 50-70= (-20$)
