Write them out as a fraction then reduce them. If theyre the same then its proportional. 
25/45 can be cancelled down to 5/9 
15/27 can be cancelled down to 3/9
So no theyre not.
        
             
        
        
        
<h2><em>The equation would be d=90t because the input is 25 for t and multiply to get 2250 feet per second</em>. </h2>
        
                    
             
        
        
        
when you solve an inequality the result is an interval when you solve an equation is a number or set ex x^2=25 x=-+5 the result is finite numbers
when you multimply an equation the sign inverses but when you solve an equation there is nothing to change 
similiarities 
you can add and subtract numbers from both sides
diving and multypling the equation or inequation by a positive numeber as i said in the beggining by multypling or dividing with a negative number the equation s sign inverses ex >= becomes <=
 
        
             
        
        
        
Answer:
Step-by-step explanation:
y = (x-1)²
vertex (1,0)
y-intercept = (0-1)² = 1
