Step-by-step explanation:
Please see the attached pictures for the full solution.
Step-by-step explanation:
4x^2 - 20 = 5
4x^2 -25 = 0

2x = 5, or -5
x = 5/2 , or -5/2
Answer: A.(3x,3y)
Step-by-step explanation:
In the given graph,
Triangle A'B'C' is an image of Triangle ABC after dilation.
Algebraic rule for dilation (with center =origin)
, where k= scale factor.
Coordiantes of A = (1,1) Coordinates of A' = (3,3)
Scale factor = 

Hence, the required algebraic rule : (3x,3y)
The correct option is A.
