7 - 5 x m
-4 x 3 
i believe these are correct if this isnt is there any other information? 
        
             
        
        
        
Answer:
The value is 
Step-by-step explanation:
From the question we are told that 
 The probability that the student knows the answer to the question is 
The probability that that the student will guess is 
The probability that that the student get the correct answer given that the student guessed is 
Here W denotes that the student gets the correct answer
 Generally it a certain fact that if the student knows the answer he would get it correctly 
So the probability the the student got answer given that he knows it is 
 
Generally from Bayes theorem we can mathematically evaluate the probability that the student knows the answer given that he got it correctly as follows 
 
=> 
=> 
 
        
             
        
        
        
The absolute value of the quantity of five times x added to nine.
This will be answer .
        
             
        
        
        
Step-by-step explanation:
the slope of a line function is always the factor of x.
in our case : -1/4
it is the ratio y/x indicating how many units y changes, when x changes a certain amount of units. 
in our case y decreases by 1 for every x increase by 4.
now, the perpendicular slope simply changes x and y upside-down and flips the sign. 
in our case it is : 4/1 = 4
so, the line function in point slope form is then (using the new slope and the point coordinates) 
y - 3 = 4(x - 1)
