Answer:
Step-by-step explanation:
3x² - 3x + 7 = 0
a = 3 ; b = -3 and c = 7
D = b² - 4ac = (-3)² - 4*3*7
 D = 9 - 84 = - 75
D = 75i²
√D = √75i² = 

 
        
             
        
        
        
Answer:
y+3 = -11/7x(x-2)
Step-by-step explanation:
 
        
             
        
        
        
Let x=0.6737373...(1)
10x=6.737373...(2)
1000 x=673.737373...(3)
(3)-(2) gives 
990x=667
x=667/990
        
             
        
        
        
Answer:

Step-by-step explanation:
We are going to find the slope by lining up the points vertically and subtract, then put 2nd difference over first.
Also you could just use  .  It is the same thing.
.  It is the same thing.
 (  5  ,   5)
-(  1  ,   3)
--------------
   4      2
So the slope is 2/4 or 1/2 after reducing.
The point-slope form a line is
 with a point on the line
 with a point on the line  given and with slope
 given and with slope  given.
 given.

We are going to solve this for y and simplify what we can because our goal is y=mx+b; this is slope-intercept form.  It is called that because it tells us the slope,m, and the y-intercept,b.
Distribute:

Add 3 on both sides:
