What is the y-intercept of f–1(x)?
wolverine [178]

Answer:

-16

Step-by-step explanation:

The given linear function is ; f(x)=\frac{3}{4}x+12

Let y=\frac{3}{4}x+12.

We interchange x and y.

x=\frac{3}{4}y+12.

We solve for y.

x-12=\frac{3}{4}y.

We now multiply through by \frac{4}{3} to get:

\frac{4}{3}x-12\times\frac{4}{3}=y.

This simplifies to;

y=\frac{4}{3}x-16.

Hence f^{-1}(x)=\frac{4}{3}x-16.

The y-intercept is -16

You roll a die four times. What is the probability that it will show an even number the first three times, then a one the last t
mezya [45]

A die has six sides so you have a *blank*/6 chance of getting a certain number.

Since there are 3 even numbers on a die and 3 odd numbers. So the probability of rolling a even number would be:

3/6 or 1/2 or 50%

There is a one, one on a die so your chance of rolling a one the last time would be:

1/6 or about 16%

Hope this helps :) If you have any more questions just ask!
