<h2>Hello!</h2>

The answer is:

The correct option is the second option:

\frac{5}{2},\frac{-1}{2}

<h2>Why?</h2>

We are given the following expression:

\frac{2+-\sqrt{9}}{2}

Now, solving we have:

First solution:

\frac{2+\sqrt{9}}{2}=\frac{2+3}{3}=\frac{5}{2}

Second solution:

\frac{2-\sqrt{9}}{2}=\frac{2-3}{3}=\frac{-1}{2}

Hence, we have that the correct option is the second option:

\frac{5}{2},\frac{-1}{2}

Have a nice day!

Answer:

The correct answer is second option

5/2, -1/2

Step-by-step explanation:

From the attached figure we can see that,

(2 ± √9 )/2

<u>To find the simplified form of (2 ± √9 )/2</u>

(2 ± √9 )/2 = (2 + √9 )/2 or (2 - √9 )/2

(2 + √9 )/2 = (2 + 3)/2 = 5/2

(2 - √9 )/2 =  (2 - 3)/2 = -1/2

Therefore simplified form of (2 ± √9 )/2 are

5/2 and -1/2

The correct answer is option 2

Which graph is the line y=-2/5x+3?
Mashcka [7]
1st we should find the point where the line intersects with the axises 
put x= 0 , so y= 3 ---- > the 1st point (0,3) 
put y=0 , so x = 7.5 ----> the 2nd point (7.5,0) 
so it's the first graph on the left
