Answer:
The x- coordinates are equal at -3.
Step-by-step explanation:
Rule needed: i^2 = -1
Standard form a + bi
(3 + 2i)(7 - 5i) FOIL
3 * 7 = 21
3 * - 5i = - 15i
2i * 7 = 14i
2i * -5i = - 10i^2 = - 10 * -1 = 10
Putting it all back together.
31 - i
Answer: C = -5

Step-by-step explanation:
17 + 15 + 23 + 23 + 23 =101 / 5 = 20.2
Mean before was 20.2
In order for the mean to be 19, all those numbers would have to add up 114 to be divided by 6 and have a mean of 19
114 / 6 = 19
114-101 = 13 is that number
17 + 15 + 23 + 23 + 23 + 13 = 114 / 6 = 19
