Answer:
point C
Step-by-step explanation:
Given: z1 = 7 - 3i and Z2 = 3 – 5i
Add the numbers with numbers and i's with i's
z1: 7 - 3i
z2: 3 - 5i
z1+z2 = 10 - 8i
the x-axis is the real number and y-axis is the imaginary numbers.
point C is at the -8i and positive 10
You Answer Is 32X21
4x7=28. 8x3=24
28x24=672
32x21=672

Answer:
functions: A, C; non-functions: B, D
Step-by-step explanation:
A relation is not a function if any input value (x) maps to more than one output value (y).
On a graph, we apply the "vertical line test." If any vertical line intersects two or more points on the graph, it is not a function. We say it fails the vertical line test. The bottom graph (D) fails the vertical line test, so is not a function.
On a mapping, such as figure B or C, any input (x-value) that is the source of two or more arrows means the relation is not a function. The map of B is not a function.
The other choices (A and C) show a functional relation.
