Answer:
Explanation:
19.
P = 2(x - 3 + 7x + 1)
= 2(8x - 2) 
= 16x - 4
20. 
P = 3y + 5 + y - 4 + 6y
= 10y + 1
        
                    
             
        
        
        
Answer:
The given line segment whose end points are A(2,2) and B(3,8).
Distance AB is given by distance formula , which is 
if we have to find distance between two points (a,b) and (p,q) is 
 =  
AB=  = 6.08 (approx)
 = 6.08 (approx)
Line segment AB is dilated by a factor of 3.5 to get New line segment CD.
Coordinate of C = (3.5 ×2, 3.5×2)= (7,7)
Coordinate of D = (3.5×3, 3.5×8)=(10.5,28)
CD = AB × 3.5
CD = √37× 3.5
      = 6.08 × 3.5
 = 21.28 unit(approx)
2. Slope of line joining two points (p,q) and (a,b) is given by 
m=
m= 
As the two lines are coincident , so their slopes are equal.
Slope of line AB=Slope of line CD = 6
 
        
                    
             
        
        
        
Answer:
1) For each value of x, a value of y is increased by 5.
x = 0, y = 5
x = 1, y = 10
x = 2, y = 15
x = 3, y = 20
------------------------------------------------------------------------------------------
2) For each two values of x, a value of y is increased by 10.
x = 0, y = -2
x = 2, y = 8
x = 4, y = 18
x = 6, y = 28
-------------------------------------------------------------------------------------------
3)
x = 0, y = 1
x = 1, y = 
x = 5, y = 3
x = 10, y = 5
-------------------------------------------------------------------------------------------------
4) 
x = 0, y = 2
x = 1, y = 17
x = 2, y = 32
x = 5, y = 77
Step-by-step explanation:
This is as easy as replacing x for the actual value show on the table.

Answer:
The probability that Kyle will pick a girl who likes football is 12.5%.
Step-by-step explanation:
The data provided is as follows:
                          Boys        Girls       Total
Basketball          10             8             18
  Football           25             7             32
   Soccer             9             19             28
  Baseball           18            22            40
    Total               62           56            118
Compute the probability that Kyle will pick a girl who likes football as follows:

             
Thus, the probability that Kyle will pick a girl who likes football is 12.5%.
