The answer is 21 which comes from 7 * 3.
Draw the four points in a complex plane. From the drawing you can see that the lenght is 4i - (-3i) = 4i + 3i = 7i, and the width is 1 - (-2) = 1 + 2 = 3.
So, the area is 7 * 3 = 21.
Yes 1 and 3 are supplementary
Answer:
It represents the millions place, so in this case 3,000,000
Step-by-step explanation:
Answer:
B. 2x-y = 8
Step-by-step explanation:
First, plug in the points (5,2) into the equation. 5 being x and 2 being y.
Then 2x-y = 8
2 (5) - (2) = 8
10 - 2 = 8
8 = 8
