Hello,
As h(x) is a bijection,
range(h(x))=dom(h^(-1)(x))={0,1,2,3}
Answer C
        
                    
             
        
        
        
4 and 8 twelves - 1 and 11 twelves
4 8/12 - 1 11/12
= 2 3/12
Answer : 2 3/12 simplified to 2 1/4 
Check answer:
2 9/12 + 1 11/12 = 4 8/12
        
             
        
        
        
Answer:
The slope of the given line and a line parallel to it is 5/2.
Step-by-step explanation:
Explanation:
Given:
5
x
−
2
y
=
11
 is the standard form of a linear equation.
A line parallel to this line has the same slope. To determine the slope, solve for 
y
 to change the equation to slope-intercept form:
y=mx+b, where: m is the slope and b is they intercept.5x−2y=11      
Subtract 5x from both sides. −2y=−5x+11
Divide both sides by −2. y=−5/−2x+11/2
Simplify. y=5/2 x −11/2
The slope of the given line and a line parallel to it is 5/2.

Answer:
He needs 1 hour 40 minutes more to get the amount of sleep he likes or 1 2/3 hours
Step-by-step explanation:
Justin likes to get 7 hours of sleep.
 He woke up after sleeping for 5 1/3 hour = 5 hours 20 mins
Number of more hours needed to get the amount of sleep he likes= 7 hours - 5 1/3 hours.
1 hour = 60 minutes 
1/3 hours = 60/3 = 20 minutes
Hours         Minutes
7                     00       when we borrow 1 hour we borrow 60 minutes
<u>5                    20</u>
<u> 1                   40</u>

He needs 1 hour 40 minutes more to get the amount of sleep he likes
or 1 2/3 hours
 
        
             
        
        
        
Answer: 42
Step-by-step explanation:
36+42 = 78
6(6) =36+42 (like in the equation) =78
