Answer:
, 
Step-by-step explanation:
This complex expression is computed from the De Moivre expression:

Given that resultant expression is entirely real, the expression is simplified into this form:


The angle is 0 radians.
Answer:
(-11,-7)
Step-by-step explanation:
U V
(-8,5) + (-3,-12)
(-8 - 3) , (5 - 12)
-11 , -7
(-11,7)
Hello!

3x + 5 = x - 10
Solve for x by isolating the variable.
Subtract 5 from both sides:
3x + 5 - 5 = x - 10 - 5
3x = x - 15
Subtract x from both sides:
3x - x = x - x - 15
2x = -15
Divide both sides by 2:
2x /2 = -15 / 2
x = -15/2.
This can be also written as y=-2x+2
First of all the - at the beginning = reflection across the x axis.
Then the first 2 is a vertical stretch of 2
the second 2 is a translation of 2 units up.
So
1.ref. across the x axis
2.vert. stretch of 2
3. translation of 2 units up
Answer
x should equal 5/42
