What number should be added to both sides of the equation to complete the square?

lubasha [3.4K]

Answer:

9 should be added to both sides of the equation to complete the square.

Step-by-step explanation:

Given : $x^2 -6x = 5$

To Find: What number should be added to both sides of the equation to complete the square?

Solution:

$x^2 -6x = 5$

Add the square of half of coefficient of x

So, the square of half of coefficient of x = $(\frac{6}{2})^2=3^2 =9$

So, $x^2 -6x +9 = 5+9$

$x^2 -6x +3^2 = 5+9$

$x^2 -2 \times 3 \times x +3^2 = 5+9$

$(x-3)^2 = 5+9$

$(x-3)^2 =14$

Thus 9 should be added to both sides of the equation to complete the square.

I AM GIVING BRAINLISEST AND 20 POINTS! Write the equation of the circle in standard form.

azamat

Answer:

$(x-4)^2+(y)^2=1$

Step-by-step explanation:

The general format for the equation of a circle is the following:

$(x-n)^2+(y-m)^2=1$

This circle will have its center at point $(n,m)$ . Please note that its center is shifted (n) units to the right of the origin, and (m) units up. Apply this knowledge to the given problem.

The circle in the given problem has its center at (4, 0). Therefore the following can be stated,

$n=4\\\\m =0$

Substitute these points into the general formula for the equation of a circle, then simplify,

$(x-n)^2+(y-m)^2=1$

$(x-4)^2+(y-0)^2=1$

$(x-4)^2+(y)^2=1$

The average wage for an electrician in CA is $25.47/hour. That is 11% above the national average. What is the national average?

yan [13]

Answer:

$22.95/hour.

Step-by-step explanation:

It is given that the average wage for an electrician in CA is $25.47/hour. That is 11% above the national average.

Let as consider x be the national average.

11% above the national average is

$x+\dfrac{11}{100}x=x+0.11x=1.11x$

The average wage for an electrician in CA is 11% above the national average. So,

$1.11x=25.47$

Divide both sides by 1.11.

$x=\dfrac{25.47}{1.11}$

$x=22.945945...$

$x=22.95$

Therefore, the national average is $22.95/hour.
