Answer:

\huge\boxed{\log10^{3x-2y}=3x-2y}

Step-by-step explanation:

\text{Use}\\\\(1)\log x=\log_{10}x\qquad(x>0)\\\\(2)\log_ab^n=n\log_ab\qquad(a>0;\ a\neq1;\ b>0)\\\\(3)\log_aa=1\qquad(a>0;\ a\neq1)\\\\\log10^{3x-2y}=\underbrace{(3x-2y)\log10}_{(2)}=\underbrace{(3x-2y)\log_{10}10}_{(1)}=\underbrace{(3x-2y)(1)}_{(3)}=3x-2y

Answer:

3x-2y

Step-by-step explanation:

log10^(3x-2y)

We know the base is base 10 since it is not written

log10 10^(3x-2y)

The log10 10 cancels

3x-2y

Write the equation of this circle in standard form.<br> please give answer?
Law Incorporation [45]

Given the center (x_0,y_0) and the radius r of a circle, its equation is

(x-x_0)^2+(y-y_0)^2=r^2

In your case, the center is (-4,0), and the radius is 2. Plug these values into the generic formula and you'll get the equation.

List from smallest to largest 7/12 1/2 2/3 4/10 1/6​
Vlad1618 [11]

Answer:

So if you're having difficulty visualizing the differences, you can rewrite them so they all have the same denominator

7/12 = 35/60

1/2 = 30/60

2/3 = 40/60

4/10 = 24/60

1/6 = 10/60

So now it's easier to see how they compare to each other.

10/60, 24/60, 30/60, 35/60, 40/60

And then simplify them or just refer to what they were before

1/6, 4/10, 1/2, 7/12, 2/3

I hope this helps!

Can someone help me with this, im not really good at math and i dont understand this :(​
cluponka [151]

Answer:

y = 2x + 4

Step-by-step explanation:

First find 2 points on the line to determine slope.

(0, 4) and (2, 8)

Slope = \frac{8-4}{2-0}=2

y = 2x + b

b = y - intercept

b = 4

y = 2x + 4
