First, add the whole numbers: 2 + 3=5. 5 + 1/2=5 1/2+ 3/4=6 1/4. 10-6 1/4=3 3/4!

I NEED HELP!! please show all work

Take the logarithm of both sides. The base of the logarithm doesn't matter.

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

$\implies \log 4^{5x} = \log 3^{x-2}$

Drop the exponents:

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

Expand the right side:

$\implies 5x \log 4 = x \log 3 - 2 \log 3$

Move the terms containing x to the left side and factor out x :

$\implies 5x \log 4 - x \log 3 = - 2 \log 3$

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

Solve for x by dividing boths ides by 5 log(4) - log(3) :

$\implies \boxed{x = -\dfrac{ 2 \log 3 }{ 5 \log 4 - \log 3 }}$

You can stop there, or continue simplifying the solution by using properties of logarithms:

$\implies x = -\dfrac{ \log 3^2 }{ \log 4^5 - \log 3 }$

$\implies x = -\dfrac{ \log 9 }{ \log 1024 - \log 3 }$

$\implies \boxed{x = -\dfrac{ \log 9 }{ \log \frac{1024}3 }}$

You can condense the solution further using the change-of-base identity,

$\implies \boxed{x = -\log_{\frac{1024}3}9}$

Rewrite the standard form equation below into slope-intercept form. x – 2y = 3

Gnom [1K]

X-2y = 3

-2y=3-x move the x over to the other side

-y=3/2 -1/2x divide both sides by 2

y=1/2x - 3/2 divide both sides by -1

Which polynomial is twice the sum of 4x^2 – 1 + 1 and - 6x^2+ x - 4?

kap26 [50]

Answer:

Step-by-step explanation:

The sum of these two polynomials is - 2 x^2 - 3. the two x variables are additive inverses and -6 x^2 and 4 x^2 equal - 2 x^2 and -3 results from -4 and 1

Multiplying the sum by 2 gives us - 4 x^2 - 6 . Answer 3
