For this case we have to by definition:
If two lines are parallel then their slopes are equal.
If two lines are perpendicular then the product of their slopes is equal to -1.
We have the following equations:
We manipulate the equation to convert it into the slope-intersection form 
Where:
m: It's the slope
y: It is the cut-off point with the y axis.
So:
From the second equation given we have:
We manipulate:
It is observed that the slopes are equal, so the lines are parallel,
ANswer:
The lines are parallel.
Answer:
3.5% Error
Step-by-step explanation:
I used this equation - 100 * (1 - (75.5/78.25)) = 3.514376...(Rounded to the tenths place you get 3.5)
Breakdown: You want to get your error to do this first you get your percent that was correct which is - (75.5/78.25)
You then subtract this by one because this will give you your margin of error as a decimal hence - (1 - (75.5/78.25))
Lastly, multiply this by 100 because you want to convert the decimal into a percent then round to the nearest tenth of a percent resulting in 3.5% error.
8x+(4*30)=6(6+30)
8x+120=6x+180
2x=60
x=30 pounds of coffee
I’m not rlly good at math but the answer should be 25.13
