The coordinates of B will be "(2, -8)".
Given:
Midpoint of AB,
(x, y) = (0, -7)
Coordinates of A,
(x₁, y₁) = (-2, -6)
As we know,
The formula of midpoint is:
→ 



→ 




hence,
→ 
Thus the above answer is correct.

Pythagorean theorem:
AC² + BC² = AB²
since this is isosceles (2 sides the same length), we can just let BC = AC and get
AC² + AC² = AB²
2AC² = AB²
AC² = AB²/2
AC = √(AB² / 2)

AC and BC are 6 meters
Answer:
It's a function that associates a real number x with a positive real number using the flowing definition: If the number is not negative (so either positive or 0) the absolute value is x. If x is negative, the absolute value is -x.
This means that to find the absolute value of x you must first determine if x is negative or not, and if it is, multiply it by -1. If it isn't, leave it as it is.
Since the absolute value is a function (of a given number), you can't just plot that number in the number line but the function (so in this case absolute value must be taken first.
The absolute value of x is never negative, so given the absolute value of x we can't determinate if x was positive or negative (if x =/ 0) before the absolute value was taken.
Answer:
n < -9
Step-by-step explanation:
<u>Divide both sides by -4, like so:</u>
-4n > 36
n > -9
<u>However, anytime you multiply/divide the inequality by a negative number, you </u><u>must</u><u> flip the sign around, like so:</u>
n < -9
