Which expression is equivalent to (f g) (5)?
f (5) times g (5)
f (5) + g (5)
5 f (5)
5 g (5)

Option A.

Step-by-step explanation:

Expression given in the question is (f g)(5).

We know when two functions are f(x) and g(x) then (f g)(x) represents the multiplication of two functions.

(f g)(x) = f(x).[g(x)]

For x = 5

(f g)(5) = f(5).g(x)

It may be represented by the operation as

(f g)(5) = f(5) × g(x)

Therefore, option A. will be the answer.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
