Answer:

2 or 4

Step-by-step explanation:

Since I do not quite understand what you mean by X X, I could think of two answers. If you are doing 5 times X=20, then X = 4, but if you are trying to do 5 times x times x, then x=2.

1+9i and 5-3i midpoint

Karo-lina-s [1.5K]

Answer:

$3+3i$

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two complex numbers (a+bi) and (c+di) points is equal to

$(\frac{a+c}{2})+(\frac{b+d}{2})i$

we have

(1+9i) and (5-3i)

substitute the given values

$(\frac{1+5}{2})+(\frac{9-3}{2})i$

$3+3i$

Find the coordinates if the midpoint of a line segment with endpoints (-3,4) and (7,9).

svetoff [14.1K]

Using the midpoint formula
$\frac{ x_{1}+ x_{2} }{2}, 
 \frac{ y_{1}+ y_{2} }{2}$
$\frac{-3+7}{2},
 \frac{4+9}{2}$
$\frac{4}{2},
 \frac{13}{2}$
$(2,6.5)$
So, your answer would be (2,6.5).
