Y = x² - 4x convert from standard to vertex form

Pepsi [2]

Answer:

$y = (x-2)^{2} -4$

Step-by-step explanation:

To complete the square: add 4 to both sides because the product of 4 as 2 as the factor which 2 * 2 so $2^{2}$

$y + ? = x^{2} - 4x + ?$

$y + 2^{2} = x^{2} - 4x + 2^{2}$

$y + 4 = x^{2} - 4x + 4$

Now we can factor the expression

$y + 4 = (x-2)^{2}$

Move the 4 to the other side to isolate y which changes the sign

$y = (x-2)^{2} - 4$

What is the distance between the two points (-8,-6) and (-2,4)?

MAVERICK [17]

Answer:

$\sqrt{136}$ = 11.66 units

Step-by-step explanation:

distance between 2 points (a,b) and (c,d) = $\sqrt{(a^{2}-c^{2} ) +(b^{2}-d^{2} ) }$

= $\sqrt{((-8)^{2}-(-2)^{2} ) + ((-6)^{2}-4^{2}) }$

= $\sqrt{136}$

= 11.66 units

Find the value of <br> x<br> x<br> that makes the expressions equivalent.<br> 2(x+9); 30+18

Vlada [557]

Answer:

$x=15$

Step-by-step explanation:

We are given the equations $2(x+9), 30+18$ to search for a value of $x$ that yields an equivalent statement. $2(x+9)=30+18\\2(x+9)=48\\x+9=24\\x=15$ .
