B
Because the number are either rising or falling
Answer:
(h o k)(3)= 3
(K o h)(-4b)= - 4b
Step-by-step explanation:
Composition of a function and its inverse function returns the input
(h o k)(3)= 3
(K o h)(-4b)= - 4b
Answer:
65
Step-by-step explanation:
They are vertical angles; so angles are congruent
*<em>Vertical angles are always congruent*</em>
<em>Congruent means equal or same.</em>
1) Since they are congruent, you form an equation.
<h2>
145 = 2x + 15</h2>
2) Solve by subtracting 15 from both sides.
<h2>
145 = 2x + 15</h2><h2>
- 15 -15</h2><h2>
----------------------</h2><h2>
130 = 2x</h2>
3) Solve by dividing 2 from both sides
<h2>
130/2 = 2x/2</h2>
4) Simplify
x = 65
Answer:
<u>x = 25</u>
Step-by-step explanation:
<u>Solving</u>
- ∠CAD = 1/2 ∡ CD
- 180° - 90° - (2x)° = 1/2 (80°)
- 2x = 90° - 40° = 50°
- <u>x = 25</u>
9 + 0.5n = 35
0.5n = 35 - 9
0.5n = 26
n = 26 : 0.5
<u><em>n = 52</em></u>
