Evaluate the following:
F(x) = 4x - 9 for f(5)

f(5)=11

Step-by-step explanation:

f(x)=4x-9

f(5)=4(5)-9

f(5)=20-9

f(5)=11

f(5) = 11

Step-by-step explanation:

F(x) = 4x - 9 for f(5)

x gets replaced with 5

f(5) = 4(5) - 9

f(5) = 20 - 9

f(5) = 11

B. Cs = 5 + 3s

Step-by-step explanation:

This is because of the placement. That is all there is to it really. 5$ is a singular cost to enter the store while the 3$ will be multiplied by S amount of shorts. Adding these two costs will get the total cost or as shown by the equation, Cs.
