1 answer:

7 0

<span>You can show the relation of both number by simply identifying th place value of each digits.
For example, the number is 555.55
=> First 5 in the left has a hundreds value, followed by tens and ones.
=> then the number next to decimal point has a value of tenths and the next is hundredths.

Now, how the find the relationship of the given number
=> Each number has 10 times difference with each other.
=> 0.05 x 10 = 0.5
=> 0.5 x 10 = 5
=> 5 x 10 = 50
=> 50 x 10 = 500
=> 555.55</span>

Descried how to derive the quadratic formula from a quadratic equation in standard form

Aleks [24]

Answer:

The standard form of a quadratic equation is:

$ax^2+bx+c=0$ , $a\neq 0$

Quadratic Formula Derivation:

$ax^2+bx+c=0\\$

$x^2+\frac{b}{a}x+\frac{c}{a} =0$

$x^2+\frac{b}{a}x = -\frac{c}{a}$

Completing the Square:

$x^2+\frac{b}{a}x +\frac{b^2}{4a^2} = \frac{b^2}{4a^2}-\frac{c}{a}$

$( x+\frac{b}{2a} )^2 = \frac{b^2-4ac}{4a^2}$

Square Root property:

$x+\frac{b}{2a} = \pm \sqrt{ \frac{b^2-4ac}{4a^2}}$

$x = -\frac{b}{2a} \pm { \frac{\sqrt {b^2-4ac}}{2a}}$

$x = \frac{-b\pm\sqrt{b^2-4ac}} {2a} }$

Solve for x: -4x - 12 < 12

aliina [53]

Seems like you are an imposter ;). This is Middle School math.

Anyways...

Answer:

x>6

Step-by-step explanation:

-4x-12<12

Add 12 on both sides.

-4x<24

Divide both sides by -4 to isolate x. Remember that if you are dividing by a negative, flip the sign!

x>6

Hope this helps!
