John exercised 20% more than Toby. So the number of hours that John exercises per week is 14 + 0.2(14) = 14 + 2.8 = 16.8.
Jenny exercises two more hours than John. So the number of hours that Jenny exercises per week is 16.8 + 2 = 18.8.
So an expression representing the number of hours that Jenny exercises after w weeks is 18.8w.

Answer:
D=
Step-by-step explanation:
Here we are required to find the distance between two coordinates. We will use the distance formula to find the distance 
The distance formula is given as 

Here we are given two coordinates as 

Substituting these values in the Distance formula given above we get



Hence this is our answer
 
        
             
        
        
        
This is a linear equation. since there is no exponent on the x, x is just to the power of 1. anything to the power of 1 is considered a linear equation. you could also do the vertical line test and find that when you plug any number in for x, none of the final answers will repeat each other. i hope this makes sense and that this helps!!
