g(x) = 3x

g(x) = 3( x )

g( f(x) ) = 3( f(x) ) ... replace every x with f(x)

g( f(x) ) = 3( 2x-1 ) .... plug in f(x) = 2x-1

g( f(x) ) = 3( 2x) + 3( -1 ) ... distribute

g( f(x) ) = 6x - 3

You are correct in saying D is the answer

A recipe calls for 3 cups of milk to make 30 biscuits. How many cups of milk will you need to make 45 biscuits?
anastassius [24]

The answer is: 4.5 cups.

The explanation is shown below:

1. You  need 3 cups of milk to make 30 biscuits.

2. Therefore, to solve the exercise you only need to multiply 45 biscuits by 3 cups and divide this by 30 biscuits.

3. Let's call the cups you will need to make 45 biscuits x. Then, you have:

x=\frac{(45)(3)}{30}\\x=4.5

4. Therefore, you will need 4.5 cups  to make 45 biscuits.

A video game club charges a fixed annual membership fee of $20 and $2 per video game rented. Let f(n) represent the total annual
djverab [1.8K]
The total cost for video rental, f(n), is the sum of the membership fee and the cost of renting video game. The latter is the product of cost per video game times n video games. The correct equation used to represent the total cost is,
                          f(n) = 20 + 2n
Since the membership is increased by 15, the new equation is,
                          f(n) = 35 + 2n

Can anyone help me please solving this maths problems not sure if. Thanks

The reason you can only compare the numerators is because the denominators are the same- leaving little comparison to really make. The numerators will determine which fraction is greater or smaller.

Ex. 4/5 or 3/5

which is greater? Which is smaller?

It can be seen that the denominators are the same, now finally comparing the numerators will answer both questions.

please vote my answer brainliest. thanks!
