The coordinates for D are (-4, -7)
First we must locate point B as it is vital to finding the midpoint of BD. To do this, we take the average of the endpoints AC since B is its midpoint.
x values = -9 + 1 = -8
Then divide by 2 for the average -8/2 = -4
y values = -4 + 6 = 2
Then divide by 2 for the average 2/2 = 1
Therefore B must be (-4, 1)
Now we know the values of E must be the average of B and D. So we can write equations for each coordinate since we know they are averages.
x - values = (Bx + Dx)/2 = Ex
(-4 + Dx)/2 = -4 ---> multiply both sides by 2
-4 + Dx = -8 ---> add -4 to both sides
Dx = -4
y - values = (By + Dy)/2 = Ey
(1 + Dy)/2 = -3 ---> multiply both sides by 2
1 + Dy = -6 ---> subtract 1 from both side
Dy = -7
So the coordinates for D must be (-4, -7)
All of the above can be used in order to prove a statement using coordinate methods.
Good morning ☕️
Step-by-step explanation:
11+y is an expression that contains a variable ‘y’
then its value depends on ’y’
examples :
if y = 0 → 11+y = 11+0 = 11
if y = 1 → 11+y = 11+1 = 12
if y = 2 → 11+y = 11+2 = 13
and so on.

Answer:
-26/8+7=15/4 or 3 3/4
Step-by-step explanation:
So this is basically a ratio and the form I use to solve these is
Is. = %
Of. 100
So we're looking for 5% of the 350,000 which will be x
X. = 5
350000. 100
Cross multiply
100x=1750000
Divide by 100
X=17500
