Solve the equation.<br><br> 9x2 + 4 = 0

Alborosie

Answer: $x = \frac{2}{3}i , -\frac{2}{3}i$

<u>Step-by-step explanation:</u>

9x² + 4 = 0

9x² = -4

$\frac{9x^{2} }{9} = \frac{-4}{9}$

x² = $\frac{-4}{9}$

$\sqrt{x^{2} } = \sqrt{-\frac{4}{9} }$

$x = +/- \frac{2}{3}i$

Help me please I am<br> so confused

Mariulka [41]

Answer:

Step-by-step explanation:

The midpoint between two points is the average of the coordinates.

mp=((x2+x1)/2, (y2+y1)/2)

In this case we are given one end point and the midpoint.

Just look at the x coordinate first.

If the mid x is 8 and the x from j is 10 we have

(10+x)/2=8

10+x=16

x=6, now for the y for j when y=6 and mid y of 5

(6+y)/2=5

6+y=10

y=4

So the coordinates of K are (6,4)
