Answer:
The other endpoint would be (-13, -11)
Step-by-step explanation:
In order to find the coordinates of an end point, we need to note that the midpoint would be the average of the two values. We'll call the unknown point P and we'll start by looking at the x values only.
(1 + Px)/2 = -6 ----> multiply by 2
1 + Px = -12 -----> subtract 1
Px = -13
Now we can do the same with the y values.
(7 + Py)/2 = -2 ----> multiply by 2
7 + Py = -4 ------> subtract 7
Py = -11
Bru are u serious ? it’s C 7 x the parable equates with the equinox of traversal is 36/5
I think u should go w/ choice A because u need to find the theoretical probability of Eric picking a black marble.......
Answer: y = 0.833333333333x + 3.16666666667

Answer:
x = -76 , y = 57
Step-by-step explanation:
5x - 6y = -38
3x + 4y = 0
------------------
use 4 to multiply equation 1
5x(4) - 6y(4) = - 38(4)
20x -24y = -152
----------------------
use 6 to multiply equation 2
3x(6) + 4y(6) = 0(6)
18x + 24y = 0
------------------------
20x - 24y = -152
18x + 24y = 0
----------------------
2x = -152
----------------
divide 2 by both sides
x = -76
--------------------
to find y, slot in the of x to either equation 1 or 2
--------------------------------
equation 2
3x + 4y = 0
3(-76) + 4y = 0
------------------------
-228 + 4y = 0
4y = 228 - 0
4y = 228
---------------------
divide both sides by 4
----------------------------------
y = 57
