x = 8, --- 12
I hope this helped :))))))))))))))))))
Answer:
Step-by-step explanation:
We are given the two functions:
And we want to find:
This is equivalent to:
Then by substitution:
Evaluate:
Therefore:
Answer:
x^2 +6x +10xi -16 +30i
Step-by-step explanation:
(x + (3+5i))^2
Rewriting as
(x + (3+5i)) (x + (3+5i))
Let 3+5i = m
(x + m) (x + m)
FOILing
x^2 + xm+xm+m^2
x^2 +2xm + m^2
Replacing m with 3+5i
x^2 +2x (3+5i) +(3+5i)^2
Distribute
x^2 +6x +10xi +(3+5i)^2
Now FOIL (3+5i)^2
( 3+5i) ( 3+5i)
3*3+ 3*5i + 3*5i+ 25i^2
= 9 +15i+15i +25(-1)
9+30i -25
-16 +30 i
Replacing that in the equation
x^2 +6x +10xi -16 +30i
3x + 2y = 12
2y = -3x + 12
y = -1.5x + 6
Y=7/11x-2/11 cmon dude just isolate y and divide
