Answer:
f-1(x)=-
x-
Step-by-step explanation:
First, switch f(x) to the variable "y".
y=-
x-8
Next, swap "x" and "y" with each other.
x=-
y-8
Next, lets move the denominator of 2 to the other side by multiplying both sides by 2. Your result will be...
2x=-3y-16
Now move -16 to the left side.
16+2x=-3y
To get "y" by itself, lets divide each side by -3. Our result is...
y=-
x-
To finish the problem off, replace y with f-1(x) and your complete answer will be...
f-1(x)=-
x-
Answer: 25/676
Step-by-step explanation:
Number of possible outcomes = 26
In other to win, one must draw must be either (A, E, I, O or U)
Therefore required drws to win = 5
First draw:
P(win) = Total required outcome / Total possible outcome
P(win) = 5/26
Second draw:
P(win) = Total required outcome / Total possible outcome
P(win) = 5/26
Therefore,
P(winning twice) = (5/26) × (5/26) = 25/676
Whats the options to chose from
It’s literally just y=5 x=2
