Answer:
x = 4.5, 4/7
Step-by-step explanation:
To find the roots of a factored equation you need to set the y value at 0, that way you can solve for x. Once you solve for x you get two quantities, which can be graphed. These two quantities are where the x intercepts are.

Answer:
$637.50
Step-by-step explanation:
P = $3000
t= 5years
r = 4.25% per annum
Interest = (p×r×t)/100
= (3000×4.25×5)/100
= $637.50
 
        
             
        
        
        
So you can use
$21.95 + $.19x = $18.95 + $.21x
        
             
        
        
        
Answer:
 y  = 8x + 3
Step-by-step explanation:
The line we are describing here is line p;
  slope of line p = 8 
   y- intercept = (0,3)
y-intercept of a line is the point where it crosses the y-axis. At this point, the x = 0 
 So; 
   Slope of the line = 8
    y-intercept  =  3 
Equation of the line; 
        y  = mx + c 
y and x are the coordinates
m is the slope 
c is the y-intercept
       y  = 8x + 3
