Answer:
It is a function
Step-by-step explanation:

The partial products are: 42 x 28 = (40 + 2) x (20 + 8) = 40 x 20 + 40 x 8 + 2 x 20 + 2 x 8 
= 800 + 320 + 40 + 16 Hope this helped.
        
             
        
        
        
Answer:
Step-by-step explanation:
B
if you multiply you will have
6x^2+8x-5
 
        
             
        
        
        
The two points we are given will tell us the slope of the line, and the first point even tells us the y intercept.
slope = (y2 - y1) / (x2 - x1) = (1 - 4) / (1 - 0) = -3/1 = -3
Since the function goes through (0,4), our y intercept is 4.
Now we can fill in our function:
<span>y = _ x + _
</span><span>y = -3x + 4</span>
