If f(x) = 1/9 x - 2, what is f-1 (x)
Snowcat [4.5K]

f(x) =  \frac{1}{9} x - 2 \\

f( - 1) =  \frac{1}{9} ( - 1) - 2 \\

f( - 1) =  -  \frac{1}{9}  - 2 \\

f( - 1) =  -  \frac{1}{9}  -  \frac{18}{9}  \\

f( - 1) =  -  \frac{19}{9}  \\

If a is an odd number, b is not divisible by 3 and LCM of a and b is P, what is the LCM of 3a and 2b?
Olenka [21]

Answer:

The LCM of 3a and 2b = 6P

Step-by-step explanation:

LCM of  3 a  and  2 b  will be  6 p

Since  a  is odd, which means it's not divisible by 2. Therefore a can be number 1, 3, 5, 7, 9, 11, .......

b  is not divisible by  3, which means b can be number 1, 2, 4, 5, 7, 8, 10, 11, .....

LCM of a and b is P

Factors of 2b can be 2 multiplied by (1, 2, 4, 5, 7, 8, 10, 11, ..... )  

Factors of 3a can be 3 multiplied by (1, 3, 5, 7, 9, 11, .......)

So, to get the LCM of 3a and 2b, since we already show the factors of a and b, Then, 3 X 2 X P (remember P is the LCM of a and b)

The LCM of 3a and 2b = 6P
