Match up each of the corresponding sides, and simplify the ratio.
That ratio is the scale factor.
Answer:
Vertex: (5, -9)
Step-by-step explanation:
fix = (x-8)(x-2)
fix = x^2 - 2x - 8x + 16
fix = x^2 - 10x + 16
a = 1, b = -10, and c = 16
To find vertex:
x = -b/2a
x = -(-10)/2(1)
x = 10/2
x = 5
y = 5^2 - 10(5) + 16
y = 25 -50 + 16
y = -9
Vertex: (5, -9)

Answer:
All real values of x where x < −1
Step-by-step explanation:
Solve the function as an inequality:
(x-3)(x+1)>0
There are two cases in this:
Both factors are greater than 0.
x-3>0 and x+1>0
x>3 and x>-1
The intersection is x >3
OR
Both factors less than 0.
x-3<0 and x+1<0
x< 3 and x<-1
The intersection is x< -1
We have obtained that the function is positive for the intervals x < -1 and x > 3. But in one of those intervals the function is decreasing and in the other is increasing.
The answer is: all real values of x where x < −1 ....
Answer:
Step 1: Write down the decimal divided by 1, like this: 
Step 2: Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)
Step 3: Simplify (or reduce) the fraction
