Answer:
perpendicular lines
Step-by-step explanation:
when the two equation are written in slope intercept form:
y = -4x -7
y = 1/4x -2
the slopes are opposite reciprocals which means they are perpendicular
A rational number is defined as a number that can be written
as a ratio of whole numbers. If it can't then it isn't.
Take the point (10,5)
5 = constant / 10
constant = 5*10 = 50
also for the point (4 , 12.5) constant = 4*12.5 = 50
Answer is 50
The equation to find percent error is:
percent error=(experimental-theoretical)/theoretical *100
So, (115-82.5)/82.5=0.393939*100
39.3939%, or 39.94%
