Answer:

B

Step-by-step explanation:

Given

x² - 18x + --- = 4 + ----

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 9)x + 81 = 4 + 81

(x - 9)² = 85 ( take the square root of both sides )

x - 9 = ± \sqrt{85} ( add 9 to both sides )

x = 9 ± \sqrt{85}  ← exact solutions

Find f(x) if it is known that f(x−6)=12x−72.
zheka24 [161]

Answer:

f(x)=12x

Step-by-step explanation

We know that f(x) is our y-coordinate and x is the x-coordinate

Next we should insert x-6 as x in the equation

This is f(x)=12(x-6)-72

But if you look at this that leads to 12x-72 (ignore y-intercept)

That is our first equation  

This means that if you take out -6 from the x

You will get f(x)=12x

(Also do you go to RSM?)
