Answer:

Step-by-step explanation:
we know that
The right bisector of the line segment JK is a perpendicular line to the segment JK that pass through the midpoint of segment JK
step 1
Find the midpoint JK
The formula to calculate the midpoint between two points is equal to

we have

substitute the values



step 2
Find the slope JK
The formula to calculate the slope between two points is equal to
we have

substitute
step 3
Find the slope of the line perpendicular to the segment JK
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of the slopes is equal to -1)

we have
----> slope of segment JK
Find m_2
substitute


step 4
Find the equation for the right bisector of the line segment JK
The equation in point slope form is equal to

we have


substitute

Convert to slope intercept form
isolate the variable y




Answer:
-16
Step-by-step explanation:
-16... using d = b²-4ac
Answer: 112
Step-by-step explanation:
Following PEMDAS, we need to add the numbers in the parenthesis first
8(7+7) becomes 8(14)
Now we just multiply 8 and 14
8(14) = 112
30=12m
you divide both sides by 12
so 30/12 is 2.5
Answer:
The equation is:

And the solution is:

Step-by-step explanation:
Given
Represent Kiran with K and Tyler with T
Kiran score is represented as:

Also, Kiran scored 223 less than Tyler.
This is represented as:

Substitute 409 for K

Make T the subject
