Subtract (-2x² +3x-5) from( 6x2 -4x+2)
Andreyy89

Answer:

8x² - 7x + 7

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Distributive Property

<u>Algebra I</u>

  • Combining Like Terms

Step-by-step explanation:

<u>Step 1: Define</u>

(6x² - 4x + 2) - (-2x² + 3x - 5)

<u>Step 2: Simplify</u>

  1. Distribute negative:                    6x² - 4x + 2 + 2x² - 3x + 5
  2. Combine like terms (x²):             8x² - 4x + 2 - 3x + 5
  3. Combine like terms (x):               8x² - 7x + 2 + 5
  4. Combine like terms (Z):              8x² - 7x + 7

Expand a logarithmic expression
ivanzaharov [21]

The logarithmic expression is

log (\sqrt{z^5}/(x^3y))

To expand the expression we have to use some properties of logarithm.

We know that log(m/n) = log (m) - log(n)

By using this property we can write,

log(\sqrt{z^5}) - log(x^3y)

Square root means to the power 1/2, so for \sqrt{z^5}, we can write z^(5/2).

log(z^(5/2)) - log(x^3y)

Now we have to use another property of logarithm.

We know that, log(mn) = log(m) + log(n)

So we will use this property to log(x^3y)

log(z^(5/2)) - log(x^3y)

log(z^(5/2)) - (log(x^3) + log(y))

log(z^(5/2)) - log(x^3) - log(y)

Now we have to use another property of logarithm.

We know that, log(a^m) = m log(a)

By using this property we can write,

(5/2)log(z) - 3log(x) - log(y)

This is the required aswer here.

The equation of a circle is given below.<br> What is its center?
svp [43]

Answer:

( \frac{2}{3}, 0)

Step-by-step explanation:

The general equation for a circle is

{(x - a) }^{2}  + {(y - b) }^{2}  =  {r}^{2}

Where a and b are the x and y values of the centre. So comparing to your equation you can see that a is 2/3 and b is 0
