Given:
The point is B(2,5) and its image is B'(1,2.5).
To find:
The scale factor.
Solution:
If a figure is dilated by the scale factor k and (0,0) is the center of then the scale factor is defined as
x-coordinate of point B' is 1 and the x-coordinate of point B is 2. So, the scale factor is
Therefore, the scale factor is 
and the correct option is D.
(2x-4)(x+5) expand with indicated multiplication
2x^2+10x-4x-20
2x^2+6x-20
the 2 answers are AB and DE
Answer:
(1,4) and (1,0)
Step-by-step explanation:
These have the same first coordinate and different second coordinates, meaning that it cannot be a function. For it to be a function, the x coordinates have to be different numbers.
Answer:
10x^3+13x^2-15x-67
Step-by-step explanation:
First you distribute- 10x^3+25x^2-40-12x^2-15x-27
you distribute the 5 through then the negative 3 through
Then you combine like terms
10x^3+13x^2-15x-67
Then that is just your answer after you add the ones with the squared together and the ones with no variables together
