Scale factor should be 20.
10 plus 20 is 30 (figure B) therefore 15 plus 20 should be 35

Answer:
(a) 3/2
Step-by-step explanation:
The scale factor is the ratio of corresponding side lengths.
sf = 63/42 = (21×3)/(21×2) = 3/2
For this case we are going to define the original coordinates:
(x, y): original coordinates.
We apply the transformation:
(x, y) -------> (-x, y + k)
We have:
-x: reflection on the y axis.
y + k: translation k units up.
Answer:
The point was reflected over the y-axis and translated up.
Answer:
14/5
Step-by-step explanation:
That " • " signifies multiplication.
g(x) = (x + 1) / (x - 2) and h(x) = 4 - x are to be multiplied together to obtain (g·h)(x):
(x + 1)(4 - x)
(g·h)(x) = --------------------
x - 2
This could be simplified.
But our task is to evaluate this product function at x = -3. So we replace each instance of x with -3:
( -3 + 1 )( 4 - [-3] ) (-2)(7)
(g·h)(-3) = -------------------------- = ----------- = 14/5
-3 - 2 -5
C. Exponential. Because the numbers are neither constant nor increasing and decreasing.
