X=-2/5

Steps:
6^x/3 +2 = 6^-14x/3
x/3+2 = -14x/3.
x +6 = -14x (multiply both sides by 3)
x = -14x - 6 (Substract 6 from both sides)
x + 14x = -6 (add 14x to both sides)
15x = -6 (collect like terms)
x = -2/5 (divide both sides by 15)

Which function represents the number of seconds, s, in d days? (Hint: The number seconds in a day is 24 × 60 × 60 = 86,400.)

vaieri [72.5K]

<em>f(d)=86,400·d</em>
if you set 1 day (d=1) you get f(1)=86,400 sec
if you set 1 day (d=2) you get f(2)=172,800 sec
...etc.

Write the quadratic function in the form f (x)= a (x - h)' + k.<br> f (x) = 3x² - 6x+6

Vlad1618 [11]

Answer:

$f(x) = 3(x - 1)^2-3$

Step-by-step explanation:

Given

$f(x) = 3x^2 - 6x + 6$

Required

Write as:

$f(x) = a(x - h)^2 + k$

In $f(x) = 3x^2 - 6x + 6$ , the coefficient of x is -6

Divide by 2: -3

Square: 9

Add 9 - 9 to the above equation

$f(x) = 3x^2 - 6x +9-9+ 6$

Split to 2

$f(x) = [3x^2 - 6x +9]-[9- 6]$

$f(x) = [3x^2 - 6x +9]-[3]$

Factorize:

$f(x) = [3x^2 - 3x -3x+9]-[3]$

$f(x) = [3x(x - 1) -3(x-1)]-[3]$

$f(x) = [(3x - 3)(x-1)]-[3]$

Factorize 3x - 3

$f(x) = [3(x - 1)(x-1)]-[3]$

$f(x) = 3(x - 1)^2-[3]$

$f(x) = 3(x - 1)^2-3$
