If the line segment point is D(-5, 10) and E(a,b) and the midpoint of the segment is F(13, -2) that mean
DE= 2*DF
You can directly find the distance of AC
Xdf= Xf-Xd= 13 - (-5)= 18
Ydf= Yf - Yd= -2 - 10= -12
Then add the distance of AB( which is 2*AC) to point D
Xe= a = Xd + 2*Xdf
a= -5 +2*18= 31
Ye= b = Yd + 2Yf
b= 10+ 2*-12= -14
<span>absolute difference between a and b:
|b-a|= </span>|-14-31|= 45
You subtract 16 from each side of the equation.
Then it will say exactly what number 'n' is.
_______________________________________
The equation is n + 16 = 9
On the left side, you subtract 16 from (n + 16) and you have 'n'.
On the right side, you subtract 16 from 9 and you have -7 .
Now the equation says n = -7
You have to find the square root of 169, then add the square root of 169 by 7
Hope this helped :)
Answer:
see below
Step-by-step explanation:
5/10 divide ?/?= 1/2
5/10 divide by 5/5 = 1/2
2. 12/15 divide ?/? = 4/5
12/15 divide by 3/3 = 4/5
3. 10/12divide ?/? = 5/6
10/12 divide by 2/2 = 5/6
4. 14/18 divide ?/? = 7/9
14/18 divide by 2/2 = 7/9
Answer:
-7
