<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

A line passes through the point (-6,9) and has a slope of 3/2. Write an equation in slope-intercept form for this line.
BaLLatris [955]

Answer:

y=3/2x+18

Step-by-step explanation:

Hi there!

We are given a point (-6,9) and a slope of 3/2

We want to write the equation of this line in slope-intercept form

Slope-intercept form is written as y=mx+b, where m is the slope and b is the y intercept

Since we already know the slope of the line as 3/2, we can substitute it as m into the equation:

y=3/2x+b

Now let's find  b

Since the equation of the line passes through (-6,9), we can use it to help solve for b

Substitute -6 as x and 9 as y:

9=3/2(-6)+b

Multiply

9=-9+b

Add 9 to both sides

18=b

Substitute 18 as b into the equation.

y=3/2x+18

Hope this helps!

*Will mark brainest!!* Write an equation in point slope form <br> (-9,7) m=4
pshichka [43]

Answer:

y-7 = 4(x+9)

Step-by-step explanation:

Point slope form is

y-y1 = m(x-x1)

where m is the slope and (x1,y1) is the point

y-7 = 4(x--9)

y-7 = 4(x+9)
