Answer:
<h2>The slope is 2</h2>
Step-by-step explanation:
Step one:
we are required to find the slope of the given data points
 A(4,6) B(5,8)
hence the x and y values correspond to 
x1=4
y1=6
x2=5
y2=8
Step two:
Required is the slope which is 
slope= y2-y1/x2-x1
Slope=8-6/5-4
Slope= 2/1
<em><u>Hence the slope of the ordered pair is 2</u></em>
 
        
             
        
        
        
It would be 56. The LCM of 14 and 8 is 56.
        
                    
             
        
        
        
Answer:
x >= 7 OR x < -8
n <= -3 AND n > -6
Step-by-step explanation:
15) 7x - 6 >= 43 OR 10x + 4 < -76
7x >= 43 + 6 OR 10x < -76 - 4
7x >= 49 OR 10x < -80
x >= 7 OR x < -8
you can draw based on this
for >= it is full dot for < it is like circle on the graph
you have to draw both x>= 7 , x < -8 on the same line because it is OR
so both ranges of x are possible
21) 3 + 2n <= -3 AND 1 - 3n < 19
2n <= -3 -3 AND -3n < 19 - 1
2n <= -6 AND -3n < 18
n <= -3 AND 3n > -18 
n <= -3 AND n > -6
so it lies between -6 and -3

Answer:
x = 16
Step-by-step explanation:
9/12 = 12/x
9x = 144
x = 16
