Anyone know the correct answer to this?
Svetllana [295]

Answer:

It should be y=4x-7

Step-by-step explanation:

M is the slope meaning Δx over Δy or rise over run

So if you look at (2,2) and count up to (3,6) the rise is 4 and the run is 1 meaning the slope is 4.

B is the y- intercept so then it would just be -7.

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

What is the equation of the line that passes through the point (6,-3) and has a<br> slope of – 3?
JulijaS [17]
(6,-3) m=-3
formula is y=mx+c
substitute: -3= 3(6)+c
-3=-18+c (takeaway 18 from both sides)
-15=c

Rewrite equation in form y=mx+c

Therefore answer is y=-3x-15

I think this is how u do it from what I can remember :)
