Answer:

f(6) = 10, f(10) = 30, f(20) = 80

Step-by-step explanation:

Plug in the values into the equation and compute. 5*6 - 20 = 10, 5*10 - 20 = 30, 5*20 - 20 = 80.

Answer:

f(6) = 10

f(10) = 30

f(20) = 80

Step-by-step explanation:

Plug in the value

$\sf{f(x)=5x-20}$

$\sf{f(6)=5(6)-20}$

$\sf{f(6)=30-20}$

$\sf{f(6)=10}$

____________

$\sf{f(10)=5(10)-20}$

$\sf{f(10)=50-20}$

$\sf{f(6)=30}$

____________

$\sf{f(20)=5(20)-20}$

$\sf{f(20)=100-20}$

$\sf{f(20)=80}$

____________

Hence, these are the answers.
