Answer:

Step-by-step explanation:
The given equation is

For this function to have an inverse, we must restrict the domain, say 
We interchange x and y to get,

We now make y the subject to get;


We divide through by 16 to get;

We now take the square root of both sides to get;


Since
, the inverse function is

1. 20 x 8 = 160 m
2.

Answer:
3/20
Step-by-step explanation:
First we must get the total amount of possibilities.
We have ten numbers(0 included) and 4 letters. 10 * 4 = 40, so 40 total possibilities.
Now, let's see how many possibilities we can have for this.
Consonants in the 4 letters are B, C, D. This means we have 3 possibilities, but we ACTUALLy have 6 since it could b then 3, or 3 then b for all the letters.
So, we end up having 6/40 which simplifies in to 3/20
