How to find the other endpoint of a line when only given the first endpoint and the midpoint?
Schach [20]
If we have a line, and the endpoints are(x₁,y₁) and (x₂,y₂), the midpoint will be:( (x₁+x₂)/2 , (y₁+y₂)/2 );

Data:
Endpoint₁: (2,-3)
Midpoint: (6,6)

Therefore:

(2+x₂)/2=6
2+x₂=12
x₂=12-2
x₂=10

(-3+y₂)/2=6
-3+y₂=12
y₂=12+3
y₂=15

Answer; the other endpoint of a line will be (10,15)

What single decimal multiplier would you use to decrease by 6% followed by a 19% increase?
s344n2d4d5 [400]
Decrease by 6% = 100 - 6 = 94

Increase this by 19%

= 19/100 x 94
= 17.86

94 + 17.86 = 111.86

\ 100 = 1.1186

Find the value of x.
Romashka-Z-Leto [24]
So a straight line equals 180 degrees so you need to subtract the 69 degrees from 180 to get 111 degrees
You then need to subtract the 1 from 111 to get 110
Now the missing angle is
5x=110
You then divide 110 by 5 to get 22
X=22
