Answer:

Hi Grif05!

Your answer is 7.1 million.

To be exact , 7182000

Step-by-step explanation:

The distance between 2009 and 2012 is 3 years so we multiply.

11x3=33.

Now we must find 33% of 5.4 million.

33 % of 5.4 million is 1782000.

33% of 5400000 = 1782000

We then add 33% of 5.4 million to itself.

We get an answer of 7182000.

Hope this helps! Tell me if I'm wrong please :)

Solve for x <br> 5(x-10)=30-15x
timofeeve [1]

Answer:

solution :

    x = 4

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    5*(x-10)-(30-15*x)=0

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 5 • (x - 10) -  (30 - 15x)  = 0

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  20x - 80  =   20 • (x - 4)

Equation at the end of step  3  :

 20 • (x - 4)  = 0

Step  4  :

Equations which are never true :

4.1      Solve :    20   =  0

Find the inverse of the function y=2x^2
Jet001 [13]

to find the inverse  exchange the x and y and then solve for y

y =2x^2

x =2y^2

divide by 2

x/2 = y^2

take the square root of each side

sqrt(x/2) =y

the inverse of y =2x^2  is sqrt(x/2)
