Answer:
i = 7.5
Step-by-step explanation:
(5-3i)+(10+5i)
(5+10)+(5i-3i)
15+2i
15=-2i
15/2-i
7.5=i
Answer:
Option A is the right answer.
146-4b = 122-1b
Reason: vertical angles
So probobillity is total sucsesses over total possible or TS/TP so
11/15 so the probobility is 11/15 or 0.73
8 x 2 + 6x + 5=0
16 + 6x + 5=0
6x+21=0
6x+21-21=0-21
6x=-21
6x/6=-21/6
x=-7/2
That's a vertical line, no slope, so no y=something.
Answer: x = -9
