No, 2(3n+3)=6n + 3 is not true.
first you distribute the 2 into 3n and 3, the problem should look like this:
6n+6 = 6n+3

2(3n+3)=6n+3 are not equal to each other because if you distribute 2 into (3n+3), then you get 6n+6 which is not equal to 6n+3

Find the requested function value.

<u>Given</u>:

Given that the functions f(x)=9 x+5 and g(x)=-4x^2-6x+3

We need to determine the value of the function (f \circ g)(-9)

First, we shall determine the value of the function (f \circ g)(x)

<u>The value of the function </u>(f \circ g)(x)<u>:</u>

Let us determine the value of the function (f \circ g)(x)

Thus, we have;

(f \circ g)(x)=f[g(x)]

               =f(-4x^2-6x+3)

               =9(-4x^2-6x+3)+5

               =-36x^2-54x+27+5

(f \circ g)(x)=-36x^2-54x+32

Thus, the value of the function is (f \circ g)(x)=-36x^2-54x+32

<u>The value of the function </u>(f \circ g)(-9)<u>:</u>

The value of the function (f \circ g)(-9) can be determined by substituting x = -9 in the function (f \circ g)(x)=-36x^2-54x+32

Thus, we have;

(f \circ g)(-9)=-36(-9)^2-54(-9)+32

                 =-36(81)-54(-9)+32

                 =-2916+486+32

(f \circ g)(-9)=-2398

Thus, the value of the function (f \circ g)(-9) is -2398

Hence, Option A is the correct answer.

Gabe has 60 coins consisting of quarters and dimes. The combined value of the coins is $9.45. Find how many quarters and dimes G
Ugo [173]
We could say that dimes = x and quarters = 60 -x

Then we use the value of the coins 

10(x) + 25(60-x) = 945

I did 945 because I am doing this in cents not dollars but the answer would still work because it is asking for the amount of coins.

10x + 1500 - 25x = 945

-15x = -555

x = 37 

Dimes = x = 37
Quarters = 60 - x = 60 -37 = 23

10 divided by 3 long division
sesenic [268]

Okay so the first thing we need to do is clarify the terms so that you know what each part of the division is:

  • The first number, 10, is called the dividend.
  • The second number, 3 is called the divisor.

What we'll do here is break down each step of the long division process for 10 divided by 3 and explain each of them so you understand exactly what is going on.

<h2>10 divided by 3 step-by-step guide</h2><h3>Step 1</h3>

The first step is to set up our division problem with the divisor on the left side and the dividend on the right side, like we have it below:

  __

3| 10

<h3>Step 2</h3>

We can work out that the divisor (3) goes into the first digit of the dividend (1), 0 time(s). Now we know that, we can put 0 at the top:

   _0_

3 | 10

<h3>Step 3</h3>

If we multiply the divisor by the result in the previous step (3 x 0 = 0), we can now add that answer below the dividend:

 _0_

3 | 10

    0

<h3>Step 4</h3>

Next, we will subtract the result from the previous step from the second digit of the dividend (1 - 0 = 1) and write that answer below:

 ___

3 | 10

- 0

__

1

<h3>Step 5</h3>

Move the second digit of the dividend (0) down like so:

 __0_

3 | 10

 - 0

-----------

10

<h3>Step 6</h3>

The divisor (3) goes into the bottom number (10), 3 time(s), so we can put 3 on top:

 __03_

3 | 10

- 0

___

10

<h3>Step 7</h3>

If we multiply the divisor by the result in the previous step (3 x 3 = 9), we can now add that answer below the dividend:

 _03_

3 | 10

- 0

__

10

 9

<h3>Step 8</h3>

Next, we will subtract the result from the previous step from the third digit of the dividend (10 - 9 = 1) and write that answer below:

  __03_

3 | 10

- 0

__

10

-9

_

1

<h3>So, what is the answer to 10 divided by 3?</h3>

Your answer is the top number, and any remainder will be the bottom number. So, for 10 divided by 3, the final solution is:

<h2>3 </h2><h2> - Remainder 1</h2><h2>Extra calculations for you:</h2>
  • Using a calculator, if you typed in 10 divided by 3, you'd get 3.3333.
  • You could also express 10/3 as a mixed fraction: 3 1/3
  • If you look at the mixed fraction 3 1/3, you'll see that the numerator is the same as the remainder (1), the denominator is our original divisor (3), and the whole number is our final answer (3).
