What is the solution set of the quadratic inequality x^2-5-0?

zzz [600]

To solve this, we just have to subtract the numbers.
$-5-0=-5$
$=x^2-5$
That's our solution set.

Have a nice day! :)

For a given data set, the equation of For a given data set, the equation of the least squares regression line will always pass t

Tju [1.3M]

Answer:

<h3>For a given data set , the equation of the least squares regression line will always passes through <u>the point (x,y)</u></h3>

Step-by-step explanation:

For a given data set , the equation of the least squares regression line will always passes through <u>the point (x,y)</u>

For :

The least-squares regression line equation always passes through the point (x, y).
The correlation "r" is the strength in relationship of a straight-line
The square of the correlation,that is $r^2$ , is the fraction of the variation in the values of y that is given by the least -squares regression of y changes on x.

Left to Right

<u>Algebra I</u>

Standard Form: ax² + bx + c = 0
Quadratic Formula: $x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

<u>Algebra II</u>

Imaginary Roots: √-1 = i

Step-by-step explanation:

<u>Step 1: Define</u>

x² - 2x + 10 = 0

<u>Step 2: Identify Variables</u>

a = 1

b = -2

c = 10

<u>Step 3: Find roots</u>

Substitute [Quad Formula]: $x=\frac{2\pm\sqrt{(-2)^2-4(1)(10)} }{2(1)}$
Exponents: $x=\frac{2\pm\sqrt{4-4(1)(10)} }{2(1)}$
Multiply: $x=\frac{2\pm\sqrt{4-40} }{2}$
Subtract: $x=\frac{2\pm\sqrt{-36} }{2}$
Factor: $x=\frac{2\pm\sqrt{-1} \sqrt{36} }{2}$
Simplify: $x=\frac{2\pm6i }{2}$
Factor: $x=\frac{2(1\pm3i) }{2}$
Divide: $x=1\pm3i$
