Answer:
<em>options: A,C,E </em>are correct.
Step-by-step explanation:
We have to find the expression equivalent to the expression:

we know that: 
Hence,
-----(1)
A)
(same as(1))
Hence, option A is correct.
B) 7 ; which is a different expression from (1)
Option B is incorrect.
C)
(Same as (1))
Option C is correct.
D)
which is a different expression from (1)
Hence, option D is incorrect.
E)
; which is same as (1)
Hence, Option E is correct.
F)
; which is not same as expression (1)
Hence, option F is incorrect.
Answer:
Well it would come out to 2x-3y=-9
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The dilation with the center of dilation at the origin and scale factor of 4 has the rule
(x,y)→(4x,4y).
Thus,
- A(-1,3)→A'(-4,12)
- B(2,1)→B'(8,4)
- C(-2,-1)→C'(-8,-4)
A'(-4,12) - option B
B'(8,4) - option C
C'(-8,-4) - option D
