Answer:
Step-by-step explanation:
We must find the inverse of the following function:
to solve this, you change f(x) by y
y=
exchange the variables:
You clear the variable "y"
9(x+2) = y
y = 9(x+2)
y = 9x +18
finally you change "y" to f ^-1 (x) =
f^-1 (x) = 9x+18
Answer:
10
Step-by-step explanation:
125/12.5
Hi!
First let's find the LCD of all of the fractions, and change all of them.
The LCD of 3, 6, 8, and 10 is 120.
Now change all of the fractions.
120/3 = 40
2 x 40 = 80
80/120
120/6 = 20
7 x 20 = 140
140/120
120/8 = 15
1 x 15 = 15
15/120
120/10 = 12
9 x 12 = 108
108/120
Now, line up all of the new fractions, and put them in order from least to greatest.
80/120, 140/120, 15/120, 108/120
15/120, 80/120, 108/120, 140/120
1/8, 2/3, 9/10, 7/6

Answer:
x = 3 and x = 11
Step-by-step explanation:
To find the app price (x) that will result in 0 annual profit, we just need to make P(x) = 0 and then find the value of x:
P(x) = -2*(x-3)*(x-11)
0 = -2*(x-3)*(x-11)
(x-3)*(x-11) = 0
To make this equation equal to zero, we just need to have (x-3) = 0 or (x-11) = 0
So, the values that give P(x) = 0 are:
(x-3) = 0 -> x = 3
and
(x-11) = 0 -> x = 11
