Answer:

I think it's y = 3 and x = 9 so 3/9 I think.

or -3/9 if the ramp goes down

or 3/9 if the ramp goes up

good luck!

If (fx)=5x, what is f^-1(x)

zysi [14]

Answer:

x/5

Step-by-step explanation:

To get the inverse function you need to leave the x alone and then switch variables ( f(x) = y)

f(x) = 5x

y = 5x

y/5 = x

Now that x is alone you switch the x for y and the y for x and you get:

x/5 = y

And this new y is the inverse function of f(x) ( f^-1(x))

f^-1(x) = x/5

please help 30 points !! in a proportional relationship when Y=2 when X=8 Which of the following equations would describe this r

Alex777 [14]

Answer:

(1)

Step-by-step explanation:

We will try:

(1) y = $\frac{1}{4}$ x => 2 = 2 (seems legit)

(2) y = 4x => 2 = 32 (nope)

(3) y = x - 6 => 2 = 2 (yes but actually no because it is proportional relationship)

(4) y = $\frac{1}{2}$ x - 2 => 2 = 2 (like the above)
