Answer:

the answer is B x= -4/3

Step-by-step explanation:

9x^2+24x+20=4

9x^2+24x+20-4=0

9x^2+24x+16=0

(3x+4)^2=0

3x+4=0

3x=-4

x= -4/3

The function f(x)=x^2 -6x+3 is transformed such that g(x)=f(x-2). Find the vertex of g(x).

Lisa [10]

Answer:

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

$g(x) = x^2 -4x +4 -6x +12 +3$

$g(x) = x^2 -10 x +19$

$g(x) = x^2 -10 x + 25 +19 -25$

$g(x) = (x-5)^2 -6$

$y= (x-h)^2 -kk$

Where h,k represent the vertex and we got:

$(h,k)= (5,6)$

(5,6)

Step-by-step explanation:

We have this original function given :

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

And we want to find the vertex for this new function $g(x) = f(x-2)$ and we have:

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

And solving the square we got:

$g(x) = x^2 -4x +4 -6x +12 +3$

And adding similar terms we got:

$g(x) = x^2 -10 x +19$

Now we can complete the square like this:

$g(x) = x^2 -10 x + 25 +19 -25$

$g(x) = (x-5)^2 -6$

The general equation is given by:

$y= (x-h)^2 -kk$

Where h,k represent the vertex and we got:

$(h,k)= (5,6)$

Mia paints interior walls at a rate of 12\dfrac{\text{m}^2}{\text{h}}12 h m 2 12, start fraction, m, start superscript, 2, end

Travka [436]

Answer:

$2,000\ \frac{cm^{2}}{min}$

Step-by-step explanation:

<u><em>The correct question is</em></u>

Mia paints interior walls at a rate of 12 m^2/h. At what rate does she paint in cm^2/min?

Remember that

$1\ m=100\ cm$

$1\ h=60\ min$

Convert m^2/h to cm^2/min

substitute the values

$12\ \frac{m^{2}}{h}=12\frac{(100)^{2}}{60}=2,000\ \frac{cm^{2}}{min}$
