For X = 2,
For X = 3,
For X = 4,
To find: Mean
Solution:
Answer:x7
Step-by-step explanation:
We have the following expressions:
x = 3 + 8i
y = 7 - i
-x * y = (- 3 - 8i) * (7 - i) = -21 + 3i - 56i - 8 = -29 -53i
2x-3y = 2 (3 + 8i) - 3 (7 - i) = 6 + 16i - 21 + 3i = -15 + 19i
-5x + y = -5 (3 + 8i) + (7 - i) = -15 - 40i + 7 - i = -8 -41i
x * 2y = (3 + 8i) * (14 - 2i) = 42 - 6i + 112i + 16 = 58 + 106i
Answer:
-x * y = -29 -53i
2x-3y = -15 + 19i
-5x + y = -8 -41i
x * 2y = 58 + 106i

Answer:
The temperature on the first day was 10 °F.
Step-by-step explanation:
Let's find the temperature in every single step starting from the fourth day:
Then, the temperature of the third day was 7 °F
On the third day:
Hence, the temperature on the second day was 17 °F.
Now, on the second day:
Therefore, the temperature on the first day was 10 °F.
