On the complex plane, the number
is mapped onto the point with coordinates
.
In other words, the x coordinate is the real part of the number, while the y coordinate is the complex part of the number.
Viceversa, if you start from a point
, you can identify the number
.
So, the endpoints of the diagonal are the points
and
. These are points A and C in the attached figure.
This means that points B and D have coordinates

So, the correspondant complex numbers are

Answer:
total=45
1/3+2/5=11/15
remaining fraction of houses=1-11/15
=4/15
reamaimg houses=4/15×45=12houses
I says every time you INCREASE by 1 degree Farenheit you go up 59 degrees C, so it is false. Same for III, if you go up or down 1 degree C that's not a change of 59 in degrees F.
That leaves B, which is right if you experiment with the math.
Answer: 11/2 x 15/4 = 165
/8 = 205
/8 = 20.625
Step-by-step explanation:
Multiple: 11
/2 * 15
/4 = 11 · 15 2 · 4 = 165
/8
Multiply both numerators and denominators.
