Find the equation of the line of symmetry of y= (x+2)(x-8).

Daniel [21]

Answer:

line of symmetry , x = 3

Step-by-step explanation:

Standard form of quadratic equation is y = ax^2 + bx + c, where a, b, and c equal all real numbers. You can use the formula x = -b / 2a to find the line of symmetry.

$y = (x+ 2)(x-8)\\\\y = (x^2 -8x + 2x -16)\\\\y = x^2 -6x -16$

a = 1, b = -6, c = -16

Line of symmetry is ,

$x = -\frac{b}{2a} = -\frac{-6}{2} = 3$

In the formula I=prt, what is the value of t

maxonik [38]

You divide both sides by pr to get t on one side.
1=prt
= 1/pr=t
So the answer is one as the numerator and pr as the denominator
1/pr

Evaluate the square root

Alexandra [31]

$\sqrt{a}=b\iff b^2=a\ for\ a\geq0\ and\ b\geq0\\\\\sqrt{\dfrac{1}{144}}=\dfrac{\sqrt1}{\sqrt{144}}=\dfrac{1}{12}\\\\\\\sqrt1=1\ because\ 1^2=1\\\\\sqrt{144}=12\ because\ 12^2=144$
