To solve by completing the square, what needs to be moved in this equation?

Mathematics
1 answer:
Elza [17]3 years ago
7 0

Answer:

To complete the square, we need to have the equation set up like this:

x^2 +4x =9

To do that, we'd need to move the 4x to the left side producing

4x + x^2 = 9

And that can be rewritten as

x^2 +4x =9

So the term that needs to be moved is -4x

Y = -3x  + 6

y - 6 = -3x

-1/3 y + 2 = x

z = x  -3

z = -1/3 y + 2 -3 = -1/3  y  - 1 

set z = 0

-1/3 y = 1

y = -3

set y = 0

z = - 1

Zina [86]
The answer is A.) 500 Year books.

The profit they would gain from each year book would be $28 since each year book costs $7 to make and sells for $35. You would simply divide 14,000 by 28 to find how many books they would need to sell in order to get their investment back which would be 500 books. 

Hope this helps.

Write in simple radical form:
WARRIOR [948]

Answer:

The answer to your question is \frac{2}{3}

Step-by-step explanation:

Here, there is a difference of squares, so just solve it and simplify

              ( 1 + \frac{1}{\sqrt{3} } ) (1 - \frac{1}{\sqrt{3} } )

Multiply the binomials

             = 1 - \frac{1}{3}

Simplify

             = \frac{3 - 1}{3}

             = \frac{2}{3}

City planners are creating a 3-dimenslonal model of a city park to find the best placement for a new tennis court the city park
xxTIMURxx [149]

The dimension of the tennis court in the scaled model is 0.6 ft long and 0.3 ft wide.

Given, a rectangular plot of land that is 1,500 ft long and 600 ft wide the scale model of the park measures 7.5 ft x 3 ft.

The actual tennis court must be 120 ft long and 60 ft wide, then we need to find the dimensions of the tennis court in the scale model.

<h3>What is a scaled model?</h3>

A scale model is a physical model which is geometrically similar to an object. Scale models are generally smaller than large prototypes such as vehicles, buildings, or people.

First, divide the original measurements by the scaled ones. We get

1500 ft. ÷7.5 ft = 200

600 ft. ÷ 3 ft. = 200

Now, divide tennis courts actual dimensions by 200. That is

120 ft. ÷ 200 = 0.6 ft

60 ft. ÷ 200 =  0.3 ft

Therefore, the dimension of the tennis court in the scaled model is 0.6 ft long and 0.3 ft wide.
