F(x) = 2x+1
f(-4) = 2(-4)+1
= -8+1
= -7

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.
Answer:
14⁻⁵
Step-by-step explanation:
Dividing two exponents with the same base has the effect of <em>subtracting</em> the bottom exponent from the top one. Following that rule, we can simplify our fraction like this:

Answer:
(x-6)^2 =40
Step-by-step explanation:
The correct answer is (x-6)^2 =40
why??
Expand (x-6)^2
x^2 -12x+36 =40
Transpos 40 to the left side
So,
x^2 -12x+36 -40
Which is
x^2 -12x -4=0
