Answer:
It looks like ur doing complex conjugates sooooo the answer is 21 - 12i
They way you show work is
(3-4i)(1+5i) - (2-i) <—— use foil method on first 2 parentheses
= 3 + 11i - 20i ^2 - 2 + i ( remember i^2 = -1)
= 3 + 11i + 20 -2 + i
= 21 + 12i
Y=mx+b
m=slope
b=yintercept
input points
when x=1
y=1
1=1m+b
and
x=2
y=-2
-2=2m+b
multilpy first equaiton by -1 and add to othe requation
-1=-m-b
<u>-2=2m+b +</u>
-3=m+0b
-3=m
y=-3x+b
1=-3(1)+b
1=-3+b
add 3
4=b
y=-3x+4
first blank is -3
second is 4
Answer:
the answer is 100 I promise
(filler) The answer is 22
