Answer:
She had 38! 
Step-by-step explanation:
28-9 is 19 then just multiply that by two which is 38
 
        
                    
             
        
        
        
 Linear equation: y = mx + c
m = slope
c = y-intercept

Solving systems of equations by graphing
Step-by-step explanation:
Where the 2 equations intersect is the solution to the systems of equations.
 
        
             
        
        
        
To find the slope, use the slope(m) formula:
 and plug in the two points
        and plug in the two points
(0, 5) = (x₁, y₁)
(-9, -4) = (x₂, y₂)


 [two negatives cancel each other out and become positive]
    [two negatives cancel each other out and become positive]
m = 1      The slope is 1
 
        
             
        
        
        
Step-by-step explanation:
This is a probability related problem. 
   Probability is the likelihood of an event to occur; 
     Pr = 
The sample space here is from 1 to 25 which is 25
A. 
Pr of a card marked 8; we have just 1 possible outcome;
        Pr(8)  =  
 
B. 
Pr  of drawing a card that is a multiple of 5; 
     Multiples of 5 = 5, 10, 15 and 25 
      Pr (multiples of 5) =  
 
C. 
Pr of drawing a card with odd numbers: 
           Number of odd numbers between 1 and 25  = 13 
      Pr(odd numbers) =  
 
D. 
Pr of drawing a number with square number on it;
         Square numbers between 1 and 25  = 1, 4, 9, 16 and 25
   Pr(square numbers) =  =
   =
