Answer:
22°C
Step-by-step explanation:
(16 + 20 + 24 + 28 + 28 + 23 + 15)/7 = 22°C
I would say B in all honesty. Others probably would want A
Answer:
The answer is C
Step-by-step explanation:
Answer: (C) x² - 4x + 5 = 0
<u>Step-by-step explanation:</u>
x = 2 ± i
⇒ x = 2 + i and x = 2 - i
⇒ x - (2 + i) = 0 and x - (2 - i) = 0
0 = (x - 2 - i)(x - 2 + i)
= x(x - 2 + i) -2(x - 2 + i) -i(x - 2 + i)
= x² - 2x +xi -2x + 4 <u>- 2i</u> -xi <u>+ 2i</u> - i²
= x² - 4x + 4 - i²
= x² - 4x + 4 -(-1)
= x² - 4x + 5

Answer: B
Explanation:
The slope from (0, 0) to (1, 4) is a rise of 4 and a run of 1, thus, m = 4/1 = 4
Answer:
Y=-2.9x+120
Step-by-step explanation:
The most simple way to solve is plug any x value into each equation and see if it works
