Solve the equation. Round to the nearest hundredth. Show work.

denis-greek [22]

Answer:

Final answer is approx x=-0.66.

Step-by-step explanation:

Given equation is $5^{-2x-1}=4^{4x+3}$ .

Now we need to solve equation $5^{-2x-1}=4^{4x+3}$ and round to the nearest hundredth.

$5^{-2x-1}=4^{4x+3}$

$\log(5^{-2x-1})=\log(4^{4x+3})$

$(-2x-1)\log(5)=(4x+3)\log(4)$

$-2x \log(5)- \log(5)=4x \log(4)+3 \log(4)$

$-2x \log(5) -4x \log(4)=3 \log(4) +\log(5)$

$x=\frac{\left(3\log(4)+\log(5)\right)}{\left(-2\log(5)-4\log(4)\right)}$

Now use calculator to calculate log values, we get:

$x=-0.65817959094$

Round to the nearest hundredth.

Hence final answer is approx x=-0.66.

<h2>Question: 3 (x+2) - 10=4 x - 6 + x</h2><h2>PART 1:</h2>

3(x+2)−10

Distribute:

=(3)(x)+(3)(2)+−10

=3x+6+−10

Combine Like Terms:

=3x+6+−10

=(3x)+(6+−10)

=3x+−4

PART 2:

4x−6+x

=4x+−6+x

Combine Like Terms:

=4x+−6+x

=(4x+x)+(−6)

=5x+−6

Answer:

5x+-6

Given a graph for the transformation of f(x) in the format g(x) = f(kx), determine the k value. two parabolas open up with f of

Sloan [31]

Answer:

I believe that the answer is k=4.

Step-by-step explanation:

Because in order for a new function to be narrower than its parent function, the absolute value of k must be greater than 1 (k > 1), and for a new function to open in the same direction as its parent function, it must be positive, that leaves with only four as our answer.
