Which is the inverse of the function f(x) = x - 9?АО1f-1(x) =x + 9B.f-'(x) = x + 9CO $-+(x) = 9 - *D.F-'-) =-X-9
kirill [66]

To solve for the inverse of the function given;

f(x)=x-9

We begin by re-writing the function as follows;

y=x-9

To now find the inverse, we interchange y for x, and vice versa, as shown below;

\begin{gathered} y=x-9 \\ \text{Now becomes;} \\ x=y-9 \end{gathered}

We now find the value of y;

\begin{gathered} x=y-9 \\ \text{Add 9 to both sides;} \\ x+9=y-9+9 \\ x+9=y \\ y=x+9 \\ \text{Therefore;} \\ f^{-1}(x)=x+9 \end{gathered}

ANSWER:

The correct answer is option B;

f^{-1}(x)=x+9

Find the equation of the line that contains the given point and has the given slope-
mylen [45]

Answer:

y-5 = -3x

or

y = -3x+5

Step-by-step explanation:

We can use the point slope form of the equation

y-y1 = m(x-x1)  where m is the slope and (x1,y1) is a point on the line

y-5 = -3(x-0)

y-5 = -3x

We can change it to slope intercept form y= mx+b by adding 5 to each side

y-5+5 = -3x+5

y = -3x+5

What is 75.3% of 1394​
Fiesta28 [93]

Answer:

1049.682 is 75.3% of 1394 or as a fraction is 1049 341/500

Step-by-step explanation:

1394/x=100/75.3

(1394/x)*x=(100/75.3)*x       - we multiply both sides of the equation by x

1394=1.32802124834*x       - we divide both sides of the equation by (1.32802124834) to get x

1394/1.32802124834=x

1049.682=x

x=1049.682

&lt; B.5 14. Multiply &amp; simplify: (3x + 4)(x + 1)​
kondor19780726 [428]

Answer:

3x^2+7x+4

Step-by-step explanation:

Using FOIL (First, outer, inner, last)

First, we multiply 3x and x to get 3x^2 (First)

We then multiply 3x and 1 to get 3x (outer)

Then 4 and x to get 4x (Inner)

Then multiply 1 and 4 to get 4 (last)

Since the quadratics are all positive, we add all the terms together to get:

3x^2+3x+4x+4. Since 3x and 4x are like terms, we add them together and simplify to get:

3x^2+7x+4

And since we can't simplify any further, that's our answer!

Hope this helps :D
