Answer:

9x^3-6x^2+3x

Step-by-step explanation:

We have the following:

\frac{27x^4-18x^3+9x^2}{3x}

which can be separeted like this:

\frac{27x^4}{3x} -\frac{18x^3}{3x} +\frac{9x^2}{3x}

and using the rule:

\frac{x^m}{x^n}=x^{m-n}

in other words we substract the exponents at the moment we make the division, and also dividing the coefficients  (\frac{27}{3} =9,\frac{18}{3} =6, \frac{9}{3} =3) we get the following:

9x^{4-1}-6x^{3-1}+3x^{2-1}\\=9x^3-6x^2+3x

the answer is: 9x^3-6x^2+3x

9x^3-6x^2+3x

Basically with this you just wanna simplify each term one-by-one.

For instance, look at the first term, 27x^4

Imagine 27x^4/3x

3 goes into 27 9 times, and x goes into x^4 4 times (cuz x to the power of 4 is just x times x times x times x)

So you’re left with 9x^3

Solve by addition ANSWER NOW
emmasim [6.3K]
Using elimination, we add the equations, but this time from left to right. This process wants to elimination a variable. So 2x plus -2x equals 0. Moving on the next variable, 6y plus -y is 5y. On to the last variable, 18 plus 12 is 30. So we have this equation, 5y=30. 30/5 is 6, so y=6. We plug 6 into y in one of the equations you choose. In this case, I'm going to use the first equation. Plugging 6, we have this equation, 2x plus 36 is 18. 18-36 is -18. We then have this equation, 2x=-18. We know -9 times 2 is -18, so our x value is -9, So, our y=6, and our x=-9.

What is the value of [-4.6]
solniwko [45]
<h2>Answer:</h2>

              The value is:

                      -4

<h2>Step-by-step explanation:</h2>

We are asked to find the value of the ceiling function: \left \lceil -4.6 \right \rceil

As we know that the ceiling function always occupy the higher value in integers.

i.e. the ceiling function act as follows:

it takes value 0 when   -1< x≤0

                       1 when  0 < x ≤ 1

                       2 when  1 < x ≤2

and so on.

As we know that:

            -4.6 lie between -5 and -4.

            Hence, we have:

            \left \lceil -4.6 \right \rceil=-4

Veronica has been saving dimes and quarters she has 110 coins in all and the total value is 18.50 how many dimes and quarters do
Lady_Fox [76]

This problem can be solved by the chicken rabbits method or you can just do simple algebra.

I.) Chicken and rabbits method

First assume all 110 coins are dimes and none are quarters.

We will have a total value of 11 dollars

Now for each dime we switch out for a quarter, we adds 15 cents to the total value.

18.50-11=7.50 dollars

There are 750/15=50 group of 15 cents in the 7 dollars and 50 cents.

This also meant that we need to switch out 50 dimes for 50 quarters.

So we have 50 quarters.

That first method is very good and very quick once you get the hang of it, now I'm going to show you the algebraic way to solve this.

Let's say there are x dimes and y quarters.

Set up equation

x+y=110

10x+25y=1850

Now solve multiply first equation by 10

10x+10y=1100

subtract

15y=750

y=50

Now we set the numbers of quarters to y so the answer is 50 quarters.

I personally recommend using algebra whenever you can because the practice is very important and you will eventually get really fast at setting up and solving equations. The first method is faster in this case but the second is more generalize, hope it helps.

11. Find the coordinates of the point located six units behind the yz- plane, seven units to the right of the xz - plane, and ei
Alexxandr [17]

Answer: I think

Step-by-step explanation:Let the coordinate of the point be (x,y,z). Since the point is located 3 units behind the YZ− plane, 4 units to the right of XZ− plane and 5 units above the XY−plane ,x=−3,y=4 and z=5 Hence, coordinates of the required points are (−3,4,5)
