I represents

then there is the imaginary part, and the real part
the i is the imaginary
the 7 is the real part
distribute
i-(7-8i)
i-1(7-8i)
i-7+8i
-7+9i
it is normally writtnen in a+bi where a is the real part and b is the imaginary part
so the answer is -7+9i
So you want to find how many miles are being flown in one hour.
There are 60 minutes in one hour so you want to find how many times 15 goes into 60 so you can then multiply that by 115.
60 / 15 = 4.
Now multiply 115 by 4,
115 x 4 = 460
Therefore the plane is flying at B. 460 mph.
Hope I helped!
Answer: Choice B)
2x+5(2x+3) = 3
============================================
Reasoning:
We start with the second equation 2x+5y = 3
Since y = 2x+3 from the first equation, we can replace every copy of y with (2x+3). This replacement is valid because y and 2x+3 are the same.
So that's how we go from 2x+5y = 3 to 2x+5(2x+3) = 3
This replacement is done to get rid of the y variable, and it allows us to solve for x later on.
