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;

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

yeah i kinda drug my way through this whole lesson because i was lazy and now im kinda in deep water so help pls

il63 [147K]

Answer:

127.5

Step-by-step explanation:

First, we need to find the value of x

since the two angles are connected to a straight line, their sum will be 180 (degrees)

$(2x+7)+(6x-9)=180^{o}$

add the angles together

$\therefore 8x-2=180$

add 2 to both sides

$\therefore 8x=182$

divide out by 8

$\therefore x = 22.75$

now we must determine which angle has the greater value (not visually)

$angle A = 2x+7$

$\therefore \angle{A} = 2(22.75)+7$

$\therefore \angle{A} = 45.5+7$

$\therefore \angle{A} = 52.5$

$angle B = 6x-9$

$\therefore \angle{B} = 6(22.75)-9$

$\therefore \angle{B} = 136.5-9$

$\therefore \angle{B} = 127.5$

$\angle{B}>\angle{A}\ \because\ 127.5>52.5$

so the answer would be 127.5

How do you find volume if you only have the surface area

Troyanec [42]

To find the volume of a cube from its surface area, first use the formula for surface area to find the length of one side of your cube. To do this, plug the surface area you're given into the formula, which is surface area = 6x^2, where x is the length of one side of the cube. Then, solve for x.
