Answer: 5,000
Step-by-step explanation: Take the number 4,615 no the rule for rounding any digit is 5 and above give it a shove aka round up 4 and below let it rest or round down go to the digit before the number you are rounding the 6 now six is above 5 so you will round this up now to round it up it will be ten so leave the 0 and carry the 1 over to the 4 add it and you will get your answer and lastly all digits to the right of the place you are rounding make them 0s.
 
        
                    
             
        
        
        
This problem can be seen as a rectangle triangle where the vertices are:
 Vertice 1: home plate
 Vertice 2: First base
 Vertice 3: second base.
 Right angle between vertice 1 and 2 and vertice 2 and 3.
 Distance between each base in 90 '.
 Calculating then the distance between home plate and second base we have:
 d = root ((90) ^ 2 + (90) ^ 2)
 d = 127.28 feets
 answer:
 the distance between home plate and second base is 127.28 feets
        
             
        
        
        
Equation 2 is the only linear one due to the fact that there is no exponent on the x or y values.

Answer:
   k = -1
Step-by-step explanation:
Put the given value of x in the equation, and solve the resulting equation for k.
   2(5 -3) +k(1 +2·5) = k - 5 - 1
   2(2) +k(11) = k -6 . . . . simplify a bit
   10k = -10 . . . . . . . . . . add -4-k to both sides
   k = -1 . . . . . . . . . . . . . divide by 10
The value of k is -1.
_____
<em>Check</em>
Use k = -1 in the original equation and solve for x.
   2(x -3) -(1 +2x) = -1 -x -1
   2x -6 -1 -2x = -x -2 . . . . eliminate parentheses
   x = 7 -2 = 5 . . . . . . add x+7; answer checks OK
