According to the problem, y = f(x) = 2x

Here the value of x = 2.

We have to put the value of x in place of x in 2x to calculate the actual value of 2x.

Therefore, after putting the value of x in 2x we get 2x = 2 x 2 = 4

This means the value of 2x is 4. This is because we have included the given value of x to get the value of 2x.

Again the value of f(x) = 2x.

Therefore, the value of f(x) = 2x = 4.

Hey There!

Here is your answer:

The proper answer to this question is "1/4".

What you have to do is subtract 3/4 from 1/2 in order to get your answer:

3*1=3
4*1=4
-
1*2=2
2*2=4

3-2=1

=1/4

Also....

In order to make 1/2 of the recipe Wanda would have to use 1/4 cups of butter. 

(Hence): Have of 3/4 is 1/4.

Therefore the answer is 1/4

Answer:

<h2> 105 tickets</h2>

Step-by-step explanation:

To solve this problem we need to model an equation to represent the situation first.

the goal is to archive $7500 in the even, bearing in mind that there is a cost of $375 fee for rent, we need to put this amount into consideration

let the number of tickets be x

75x-375>=7500--------1

Equation 1 above is a good model for the equation

we can now solve for x to determine the number of tickets to be sold to archive the aim

75x-375>=7500--------1

75x>=7500+375

75x>=7875

divide both sides by 75 we have

x>=7875/75

x>=105 tickets

so they must sell a total of 105 tickets and above to meet the target of $7500 with the rent inclusive

Sati [7]

Answer: Hello there!

initially Maria has 6 red marbles, 6 blue marbles, and 4 green marbles.

You know that in the first pick, Maria gets a green marble ( this means that now there are 3 green marbles left)

Now we want to know the probability that she gets a red marble on the second pick.

Now there are 6 + 6 + 3 = 15 marbles in the bag, and 6 of them are red ones. Then the probability of getting one red is the number of red ones divided by the total amount ( which is the ratio of red marbles to total marbles)

this is 6/15.

now you can see that there is no 6/15 in the options, so we need to see which one is equivalent.

if we took the option C, 2/5, and multiply both denominator and numerator by 3, we get (3*2)/(3*5) = 6/15, then 2/5 and 6/15 are equivalents.

Then the correct answer is C.
