Answer:
   f(x) = -2x +7
Step-by-step explanation:
The 2-point form of the equation for a line is suitable for this. For points (x1, y1) and (x2, y2), the equation is ...
   y = (y2 -y1)/(x2 -x1)(x -x1) +y1
For the given points (0, 7) and (3, 1), the equation is ...
   y = (1 -7)/(3 -0)(x -0) +7
   y = -6/3x +7 . . . . . . . . simplify. 
We can use f(x) for y to get ...
   f(x) = -2x +7
 
        
             
        
        
        
Answer:
+ 10 and + 7
Step-by-step explanation:
Given
2x² + 7x + 5
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × 5 = + 10 and sum = + 7
 
        
             
        
        
        
Find unit rate of pages read per minute:
(5/8)/(2/3)
(5/8)*(3/2)
(5*3)/(8*2)
(15)/(16)
15/16
