Ok so for the first one it’s super simple I’m gonna do it as less complicated so it can help you :)
So first we need to convert the mixed number to an improper fraction 
1 4/5 = 9/5 
Now we need to reduce the numbers greatest common divisor which is 3 
3/5 x 6 
Now multiply the numbers 
Your answer is 18/5 I hoped this help 
Now for the second one 
this one is a little more complicated and I don’t know how to make it sound easier so I’m gonna tell you the answer which is 580/21 
The last one is the same steps we did for the first one which is 27/20 
I hoped this helped you it is a little difficult but you’ll get the hang of it :)
        
             
        
        
        
Answer:  The answer is Yes.
Step-by-step explanation:  Given in the question that Radric was asked to define "parallel lines" and he said that parallel lines are lines in a plane that do not have any points in common. We are to decide whether Radric's definition is valid or not.
Parallel lines are defined as lines in a plane which never meets or any two lines in a plane which do not intersect each other at any point are called parallel. 
Thus, Radric's definition is valid.
 
        
                    
             
        
        
        
Answer: 2
Steps:
f(-2) = 1/2x^2
f(-2) = 1/2(-2)^2
f(-2) = 1/2(4)
f(-2) = 2
