Answer:
I remember learning this but not all that clear cuz I made little pictures in every box but wouldn't the answer be $8 cuz 2$×4
The perpendicular bisector goes through the midpoint.
What is the midpoint of the 2 points?
We simply add up the x points and divide by 2. Then we add up the y points and divide by 2.
So,
Midpoint is:

Also, the perpendicular bisector's slope is the negative reciprocal of the line's slope.
The slope of the line is change in y points divided by change in x points.
Slope =

The slope (m) of the perpendicular line (negative reciprocal) is basically:

Equation of line is:

m is the slope (what we got "2")
x1 and y1 are the respective point where it passes through (which is the midpoint, which is (-3,2)
So, equation of perpendicular bisector is:
Answer:
If your looking for I the answer is -3
Step-by-step explanation:
Simplify both sides of the equation
1/2(4i+8)=-2 - Distribute
(1/2) (4i) + (1/2) (8) = -2
The subtract 4 from both sides
Then divide both sides by 2
Answer:
Jeremiah travels at 26.667 mi/hr and Ermias travels at 18.667 mi/hr.
Step-by-step explanation:
Say Ermias' speed is 's' and Jeremiah's is 'v'
distance = rate * time
distance = ( v * time) + ( s * time)
v = s + 8
240mi = ( (s+8) * 8 ) + ( s + 8)
240 = (8s +64) + s + 8
240 = 9s + 72
240 - 72 = 9 s
168 = 9 s
18.6666667 = s
v = 18.6666667 + 8
v = 26.6666667
