Answer:
3-i
Step-by-step explanation:
1-5i + 2 +4i
We add the real parts
1+2 =3
We add the imaginary parts
-5i + 4i = -1i
The complex number is
3-i
Answer:
x=-3
y=3
(-3-3i)(3+5i)
Step-by-step explanation:

and we have that must equal
6-24i
3x+5y=6
5x-3y=-24 and if we work it we found out that the solutions are
x=-3 and
y=3
Answer:
Step-by-step explanation:
RS points east; R'S' points north, so there has been a rotation 90° CCW.
After that rotation, point S would be at (1, -1). It is actually at (1, 1), so has been shifted 2 units upward.
A sequence that does the desired mapping is
- c. rotation of 90° CCW about the origin
- b. translation 2 units up
Answer:
C
Step-by-step explanation:
Total of 40 cups and 25 of them are chocolate so the proportion for chocolate would be 25/40
