x = (1 + i)√2/2Step-by-step explanation:
Simplify the left side and compare:
n ÷ (√2/2 - √2i/2) = nxn ÷ ((√2 - √2i)/2) = nxn × 2/√2(1 - i) = nxn × √2(1 + i)/(1 - i)(1 + i) = nxn ×√2(1 + i)/(1 + 1) = nxn × (1 + i)√2/2 = nxx = (1 + i)√2/2Related Questions

what is x?
Answers
The equation that passes through (3,6) and is perpendicular to 3x - 4y = - 2
a
y = - 4/3x + 3 1/3
b
y = - 3/4x + 10
c
y = - 4/3x + 10
d
y = 3/4x + 10
Answers
Answer:
C
Step-by-step explanation:
We want the equation of the line that passes through (3, 6) and is perpendicular to:
[tex]3x-4y=-2[/tex]
First, convert the second equation into slope-intercept form:
[tex]-4y=-3x-2\Rightarrow \displaystyle y=\frac{3}{4}x+\frac{1}{2}[/tex]
So, we can see that the slope of the line is 3/4.
The slopes of perpendicular lines are negative reciprocals of each other.
Therefore, the slope of the new line is -4/3.
It passes through the point (3, 6).
We can use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Substitute:
[tex]\displaystyle y-(6)=-\frac{4}{3}(x-3)[/tex]
Distribute:
[tex]\displaystyle y-6=-\frac{4}{3}x+4[/tex]
Therefore:
[tex]\displaystyle y=-\frac{4}{3}x+10[/tex]
The answer is C.

Answers
Answer:
Step-by-step explanation:
ccording to the question
3x + 7x = 350
10x =350
X = 35
Therfore
3x = 35 *3 = 105
7x = 35 *7 = 245
Follow me and mark me as a brainliest
Step-by-step explanation:
let ratio be 3xand7x
now,
3x+7x=350
10x=350
x=350/10
x=35
then,
3x=3×35=105
7x=7×35=245

What is Line segment?
Line segment is a part of the line which have two endpoints and bounded by two distinct end points and contain every point on the line which is between its endpoint.
Given that;
To check the point at which a tangent line meets a circle is called the point of tangency.
Now, We know that;
A line which touches the circle at a single point is known as a tangent to a circle.
And, The point where tangent meets the circle is called point of tangency.
Thus, The given statement is true.

awnser im believe it is 24 i think
Answer:
20 units square
Step-by-step explanation:
do the Pythagoras theorem
a²=b²+c² ⇒ a=√b²+c²
if b is 4 and c is 2 an a is the unknown
so a=√(4)²+(2)²
a=√20
then get the rule of the area of the square
Area of the square= s²
s=a=√20 (a is the hypotenuse of the triangle and also a side in the square)
so s²=20
Area of the square=20 units square

Answer:
There would be a y-intercept of one and a slope of -3/4.
Step-by-step explanation:
Negative slope means it will increase going left.
3/4 is the slope 3 rise/ 4 run
the y intercept is 1, so the line will cross the y axis at the 1 point.
