Answer:
y - 4 = (9/4)(x - 4)
Step-by-step explanation:
Here we're given the slope (9/4) of a line and one point (4, 4) on the line.  The easiest form of the equation of a straight line to use here is the point-slope form:
y - k = m(x - h).
Here h = 4 and k = 4; the slope is m = 9/4.
Thus, the desired equation is
y - 4 = (9/4)(x - 4)
 
        
             
        
        
        
Answer:
Approach: Difference of Squares Pattern

Step-by-step explanation:
The given binomial is:

We can rewrite to obtain:

This is a difference of two squares, so we will factor using difference of squares pattern.
Recall that:

If we let 

and 

Then we can factor the given binomial to obtain:

Answer:
See Below
Step-by-step explanation:
First, isolate x. To do that add 3.5 to each side
x - 3.5 =  -3.1
   +3.5    +3.5
x= 0.4
