It seems that the expression is - 7x + 3y - 2 + 6x -1 - y^2
like terms: 
-7x + 6x = - x
3y stands alone
-2 - 1 = -3
- y^2 stands alone
Answer: - x + 3y - 3 - y^2
[note: if the last term is not y^2 but 2y, then you have to combine +3y - 2y = y and the answer would be - x + y - 3]
        
                    
             
        
        
        
We are given 
Andre rode his bike at a constant speed he rode 1 mile in 5 minutes
Firstly, we will find constant speed
In 5 minutes , distance travelled =1 miles
so, we get speed

Let's assume T is time in minutes
D is the distance in miles
we  know that

so, we can plug value
and we get 

so, we get
