Step-by-step explanation:
Hey ..but there is nothing from which question can be equated ..
like if they are equal to zero..
or 
(4x+45)=(5x-18)
i am giving answer for both scenarios
(4x+45)=0
4x=-45
x=-45/4
x=(-11.25)
(5x-18)=0
5x=18
x=18/5
x=3.6
Incase if they both are equal to each other...
(4x+45)=(5x-18)
(45+18)=(5x-4x)
63=x
x=63
Hope it helps you
Have a nice day
 
        
                    
             
        
        
        
Answer:
The initial value of the function is 25 and the rate of change is - 5.
Step-by-step explanation:
The table gives the ordered pairs of linear relation and they are (1,20) and (3,10).
Now, the equation of the linear relation that includes those ordered pairs will be  
 
⇒ y - 10 = - 5(x - 3)
⇒ y - 10 = - 5x + 15
⇒ y = - 5x + 25
Therefore, the initial value of the function is 25 and the rate of change is - 5. (Answer)
 
        
             
        
        
        
If you would like to know the total length of rope Jared has, you can calculate this using the following steps: 
12.75 feet * 4 pieces = 12.75 * 4 = 51 feet
The correct result would be A: 51 feet.
