Can someone please help me?(Fill in the blanks) This is on Khan Academy too, I need it ASAP! if you answer right I'll mark you B

Travka [436]

First divide both sides by 2:

$2x^2+7x+6=0\implies x^2+\dfrac72x+3=0$

Move the constant term to the right side:

$x^2+\dfrac72x=-3$

Since

$(x+y)^2=x^2+2xy+y^2$

we want to have

$2y=\dfrac72\implies y=\dfrac74$

Then

$\left(x+\dfrac74\right)^2=x^2+\dfrac72x+\dfrac{49}{16}$

So in our equation, we need to add 49/16 to both sides in order to complete the square:

$x^2+\dfrac72x+\dfrac{49}{16}=-3+\dfrac{49}{16}$

$\implies\left(x+\dfrac74\right)^2=\dfrac1{16}$

For the function f(x) = 2 - 3x, find f(-4). Options are in the picture.

Kitty [74]

You just have to plug in -4 into
$f(x) = 2 - 3x$
This implies that,
$f( - 4) = 2 - 3( - 4)$

$f( - 4) = 2 + 3(4)$
$f( - 4) = 2 + 12$
$f( - 4) = 14$

Can someone please show me how<br><br> 19169000*e^(0.15)= 222712201<br><br> When e= 2.7182818284?

Ierofanga [76]

Answer:

It doesn't. x = 22 271 201

Step-by-step explanation:

You are going to need a calculator no matter how you do it.

$x =19 169 000 \times e^{0.15}$

(a) The direct method

$x = 19 169 000\times 2.718 281 828^{0.15} = 19 169 000 \times 1.161 834 243 = 22 271 201$

(b) The indirect method

$\ln \left (19 169 000\times 2.718 281 828^{0.15} \right ) = \ln(19 169 000) + 0.15 = 16.768 805 + 0.15 = 16.918 804\\\\e^{16.918 804} = 22 271 201$
