Answer:
Substitution method can be used
Step-by-step explanation:
Given the system of equations
y = 2x-1 ....1
-12x + 3y = 9 ....2
The best method to use id the substitution method
Substitute equation 1 into 2;
From 2;
-12x + 3y = 9
-4x + y = 3
-4x + 2x-1 = 3
-2x -1 = 3
-2x = 3+1
-2X = 4
x = -4/2
x = -2
Substitute x = -2 into 1
y = 2x - 1
y = 2(-2)-1
y = -4-1
y = -5
Hence the solution to the system of equation is (-2, -5)
Answer:
E
Step-by-step explanation:
is the same as
· 
This can be simplified to 9 · 
And the square root of -1 is i,
so this equals 9i
Given:
Rule of transformation is
.
Point = (-5,6)
To find:
The missing values in the given steps of transformation.
Solution:
Step 1: A: (-5, 6).

Step 2: Substitute x and y into 

Step 3: Do the math:
Point A' is at (-1 ,4 ).
Therefore, the coordinates of the point (-5,6) after the transformation are (-1,4).
The midpoint formula is basically just the average of the two points. Here it is:

Then, you plug the points in. The answer is (-13,-5/2) or
C
