Step-by-step explanation:
step 1
Find the midpoint of the given line segment
we know that
The formula to calculate the midpoint between two points is equal to
we have

substitute the values
step 2
Find the equation of the perpendicular bisector
we know that
The equation of a perpendicular bisector is equal to the x-coordinate of the midpoint, because is a vertical line (parallel to the y-axis)
therefore
the equation is equal to

Answer:
-4/3
Step-by-step explanation:
Slope: (y2-y1)/(x2-x1)
(-5-3)/(-3+9) = -8/6 = -4/3
The slope is -4/3
Answer:
So the probability of drawing a second red marble is 8 out 10 or 0.8.
Step-by-step explanation:
It seems to me that if one red marble is already gone, there are 8 red marbles left out of a total of 10 marbles.
So the probability of drawing a second red marble is 8 out 10 or 0.8.
Answer:
A
Step-by-step explanation:
X^2 + 6X + 8 =3
TRANSPOSE 3 TO LEFT
X^2 + 6X + 8 - 3 = 0
CALCULATE
X^2 + 6 X + 5 = 0
