A portfolio is efficient if one is unable to find a competing portfolio with a higher expected return and the same or lower rate of volatility.
<h3>The need for classifying portfolios between efficient and inefficient</h3>
Classification of portfolios are critical to investors. They help investors to make decisions regarding which portfolio to invest in.
Investors usually stay away from inefficient portfolios as a pose a higher risk relatively.
A portfolio is inefficient if there is another portfolio that has a higher return without a higher risk of volatility.

Answer:
x^2+2x+y^2−2y−7=0
Step-by-step explanation:
The method from converting to standard to general is very simple
this equation in standard form would be
(x+1)^2+(y-1)^2=9
This is because whatever the center of the circle is, you take the negative/positive version of that number
The center is at -1, 1. So it would flip to be put into the equation as 1, -1.
9 is the radius^2.
The radius is 3.
To convert to general form you just simplify
x^2+1+2x = (x+1)^2
y^2 + 1 -2y = (y-1)^2
x^2 - 2x + y^2 - 2y + 2 = 9
get the nine on the left side
x^2 -2x +y^2 - 2y 2 - 9 = 0
x^2+2x+y^2−2y−7=0

Answer:
X-coordinate = 3
Step-by-step explanation:
2x - y = 6
<u> x + y = 3 </u>
3x = 9
3x/3 = 9/3
x = 3
2 (3) - y = 6
6 - y = 6
-y = 6 - 6
y = 0
( 3, 0 )
3 is the x-coordinate of your solution.
Answer:
yes
Step-by-step explanation:
A difference of squares has the form a² - b² = (a - b)(a + b)
note that 36z² = (6z)² ⇒ a = 6z and 9 = 3² ⇒ b = 3
36z² - 9 is a difference of squares and factors as (6z - 3)(6z + 3)
