The midpoint of AB is M(7,-5). If the coordinates of A are (6, - 7), what are thecoordinates of B?
Answers
Final answer:
To find the coordinates of B, we use the formula for finding the midpoint of a line segment. By plugging in given values and arranging the equation, we get B(8, -3).
Explanation:
To find the coordinates of B, you'd use the formula for the midpoint of a line segment. The midpoint is calculated as follows - ((x1+x2)/2, (y1+y2)/2). Here, the coordinates of the midpoint M(7,-5) and A(6, -7) are given.
Plugging these in the formula:
7=(6 + x2)/2
-5=(-7+ y2)/2
By cross multiplying and arranging the equations, we can find the value of x2 and y2 - these will be the coordinates of point B.
Solving the equations gives B(8, -3) as a result.

Step-by-step explanation:
−12−2−−55=? question one
In the first fraction, the negative numerator and negative denominator cancel each other.
Since the the second fraction is negative and you are subtracting, remove the negative sign and switch the operation to addition.
The equivalent equation is
122+55=?
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(12/2, 5/5) = 10
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(122×55)+(55×22)=?
Complete the multiplication and the equation becomes
6010+1010=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
60+1010=7010
Since 70 divided by 10 equals 7 then,
7010=7
Therefore:
−12−2−−55=7
Question 2
−81+6−3=?
In the second fraction, move the negative sign from the denominator to the numerator and the value remains the same.
The equivalent equation is
−81+−63=?
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(-8/1, -6/3) = 3
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(−81×33)+(−63×11)=?
Complete the multiplication and the equation becomes
−243+−63=?
The two fractions now have like denominators so you can add the numerators.
Then:
−24+−63=−303
Since -30 divided by 3 equals -10 then,
−303=−10
Therefore:
−81+6−3=−10
Solution by Formulas
Apply the fractions formula for addition, to
−81+6−3
and solve
(−8×−3)+(6×1)1×−3
=24+6−3
=30−3
=−10

Add 12 to both sides
2|n| = 16 + 12
Simplify 16 + 12 to 28
2|n| = 28
Divide both sides by 2
|n| = 28/2
Simplify 28/2 to 14
|n| = 14
Break down the problem into these 2 equations
n = 14
-n = 14
Solve the 1st equation: n = 14
n = 14
Solve the 2nd equation: -n = 14
n = -14
When you collect all solutions;
n = ±14
