Answer:

Step-by-step explanation:
step 1
Find the slope of segment HI
The formula to calculate the slope between two points is equal to

we have
H (-4,2), and I (2,4)
substitute the given points


simplify

step 2
Find the slope of the perpendicular line to segment HI
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

we have

so

step 3
Find the midpoint segment HI
we know that
The formula to calculate the midpoint between two points is equal to
we have
H (-4,2), and I (2,4)
substitute
step 4
we know that
The perpendicular bisector of HI is a line perpendicular to HI that passes though the midpoint of HI
Find the equation of the perpendicular bisector of HI in point slope form

we have

substitute

step 5
Convert to slope intercept form

Isolate the variable y



step 6
Convert to standard form

where
A is a positive integer
B and C are integers

Adds 3x both sides

see the attached figure to better understand the problem
Answer:
Area of a trapezoid= (big base+small base)/2 x height
A=(67+54)/2 x 18
A=60.5 x 18
A=1089
They told me to answer a bunch of questions best of luck tho
Answer:
Median=7
Lower quartile=3.5
Upper quartile=8.5
Interquartile range=5
Step-by-step explanation:
Since the margin of error is 5%, the minimum of supporters will be less than the maximum of disapprovers.
So the third option will be correct. You cannot make certain conclusions based on this survey.
