Step-by-step explanation:

1. plug in 4 for F(x) making 4=x:

$f(4)=4(4)+5$

2. multiply 4 and 4:

$f(4)=4(4) +5$ ⇒ $f(4)=16+5$

3. Add 16 and 5 to get your answer:

$f(4)= 16+5$ ⇒ $f(4)=21$

Answer: 13.69

Step-by-step explanation:

$82.14/6=$

Multiply 82.14 by 100 to make it a whole number; since you're modifying the number, you must also multiply 6 by 100 in order to keep it balanced.

Answer:

a = 9, b = 3, c = 0

Step-by-step explanation:

f(x) = (1/3)^x

a = f(-2) = (1/3)^-2= 9

b = f(-1) = (1/3)^-1 = 3

c = f(0) = (1/3)^0 = 1

whenever something is to the power of 0, the answer will always be 1
