Answer:</h2><h3>False</h3><h2>
Step-by-step explanation:</h2>
The inverse is not a function because this function is not one-to-one, that is, a function 
has an inverse function if and only if there is no any horizontal line that intersects the graph of at more than one point, this is called the Horizontal Line Test for Inverse Functions. Thus, if you take an horizontal line it will pass through two points as indicated in the figure below. In conclusion, this function hasn't an inverse function.
Answer:
See below.
Step-by-step explanation:
1.
(a) < PMR
(b) < QMR
(c) < QMN
(d) < RMN
2. m < C = 4x - 6
= 4(25) - 6
= 100 - 6
= 94 so < C is obtuse.
3. 8x + 2 = 90
8x = 90 - 2
8x = 88
x = 11.
4.
(a). < DBA and < DBC are right angles (90 degrees) because BD is perpendicular to AC.
(b) < DBA and < DBC are adjacent and they share the ray BD.
(c) < DBe and < ABE are complementary.
(d) < DBA and < DBC are supplementary
(e) 90 - 40 = 50 degrees
(f) 180 - 40 = 140 degrees.
(g) As the angles are complementary
3x + 2 + 4x + 4 = 90
7x = 90 - 2 - 4
7x = 84
x = 12.

Step-by-step explanation:
The question is incomplete; However

Determine coordinates of P
When line segment is divided in ratios, the following formula calculates the coordinates;
In this case;
So, the coordinates of P is calculated as thus
Hence, the coordinates of P is
<span>A
hair stylists works ¼ to trim customer’s hair
=> 1/6 to style customer’s hair
=> 1/6 + ¼
Find the least common multiple of both denominator:
=> 1/6 + ¼ = 10/24
Simplify
=> 5/12
Now, he works 3 1/3 hour each day in 5
days
=> 3 1/3 x 5
=> 16 ½ hours in 5 days
Now, divide
=> 16 ½ divided by 5/12
=> 39 ; approximately 39 customer in 5 days can a hairstylist accommodate.</span>
