Since they are complementary, they both add up to 90 degrees. So, 90-35=55 degrees.
The measure of angle B is 55 degrees.
Answer: If you do some research you'll see color change is part of a chemical change, while a phase change is part of a physical change. For example: ice changing into water, or water changing into gas.
Answer:
y= 9
Step-by-step explanation:
-2 + 9 =7
start at -2 go to the postive side by 9 and you land on 7
idk # 2 tho sorry
Answer:
Step-by-step explanation:
<u>Find b first:</u>
- b = 3/x + 3/y
- b = (3x + 3y)/xy
<u>Find 1/b:</u>
- 1/b = 1 : (3x + 3y)/xy
- 1/b = xy / (3x + 3y)
Answer:
No
Step-by-step explanation:
If (x - 9) is a factor then x = 9 is a root and f(9) = 0
f(x) = 4x³ - 28x² - 36x - 27, hence
f(9) = 4(9)³ - 28(9)² - 36(9) - 27
= 2916 - 2268 - 324 - 27 = 297
Since f(9) ≠ 0 then (x - 9) is not a factor of f(x)
