Answer:
A. -4 + 6i
Step-by-step explanation:
Cause as we can see... (-2 - 2i)+(10-4i)
We get when we multiply 2x2=4i
Next 10-4=6
Hope it helped u
Answer:
1, 1/2
Step-by-step explanation:
the coordinates would be Oak station(8,8) and Pine Station(-6,-7).
The midpoints would be
=[8+(-6)]/2 , [8+(-7)]/2
=2/2 , 1/2
=1, 1/2
Yes, you just times one of the equations by a numberr to make it cancel out with the other. For instance:
2x + 6 y = 10
4x + 2y = 16
If we multiply the equation 2x + 6 y = 10 by 2 we get the following
2x + 6 y = 10
-2(2x + 6 y) = -2(10)
-4x -12y = -20
Now we use this new equation.
-4x -12y = -20
4x + 2y = 16
As you can see, you can cancel out the x and solve for y now.
