Answer:
A.2
Step-by-step explanation:
We know that |x|² = 13 and x = 3+bi:
(3+bi)² = 13
3² + b² = 13
9 + b² = 13
Subtract 9 from each side:
9 + b² - 9 = 13 - 9
b² = 4
Take the square root of each side:
√b² = √4
b = 2
Answer:
-3
Step-by-step explanation:
Just put that trust me
Answer:
x=12
Step-by-step explanation:
move the 3 to the other side to get x by itself.
check: 12 + 3 = 15
Replace x in g(x) by 3x+1 and you get:
(4(3x+1)+2)/3 = (12x+4+2)/3 replace now x by 0 and solve
(12*0+6)/3 = 6/3 = 2
So the answer is 2
