Answer:
Step-by-step explanation:
No c
as she was initially 300m away from the bridge (distance from bridge=300m) (time=0) so it was her starting point.
and after 6 minutes (time=6min) she reached the bridge. (distance from bridge = 0m)
Answer:
x = 7
y = -7/2
Step-by-step explanation:
(x+6i)=(3-i)+(4-2yi)
First look at the real parts
x = 3 +4
x = 7
Then look at the imaginary part
6i= -i -2yi
6 = -1-2y
Add 1 to each side
6+1 = -2y
7 = -2y
Divide by -2
7/-2 = y
For N it is 2 since you multiply 4 times 2= 8, 2 times 2=4
8-4=4
