I know this but I can't remember how to do the process.
The answer is z = 3 + i
z = a + bi
conj(z) = a - bi
conj(7 + 3i) = 7 - 3i
<span>(conj)z + 2z = 2 + 4i + conj(7 + 3i)
</span>a - bi + 2(a + bi) =<span> 2 + 4i + 7 - 3i
</span>a - bi + 2a + 2bi =<span> 2 + 4i + 7 - 3i
</span>3a + bi = 9 + i
From here:
3a = 9 and bi = i
a = 9/3 b = i/i
a = 3 b = 1
z = a + bi
z = 3 + 1 * i
z = 3 + i
Answer:
-(m-6)=3m+14
-m+6=3m+14
I would appreciate if my answer is chosen as a brainliest answer
Answer:
7/12
Step-by-step explanation:
add up all of the buttons
30+40+50=120
add up all of the blue and red buttons
30+40=70
then divide the added values
70/120
simplify
7/12
