An inequality to model this would be
7x + 8y ≥ 336.
We multiply the number of minutes running, x, by the number of calories burned each minute by running, 7.  We multiply the number of minutes swimming, y, by the number of calories burned each minute by swimming, 8.  Adding these together, it needs to be greater than or equal to 336, since she wants to burn at least that many calories.
        
             
        
        
        
Step-by-step explanation:
LET THE Point 1 A and point 2 is B
(AB) ^2=(-9-(-3))^2+ (5-(-6))^2+(-4-7)^2=278
AB=16.67 length unit
Midpoint 
X=-9-3/2 =-6
Y=5-6/2=-0.5
Z=-4+7/2=-1.5
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
Given the sets F and H of real numbers defined as given:
F={w | w>3}
H={w | w>6}
To write a set in interval  notation, we use these brackets, (  ) for < or > while we use [ or ] for  .
.
Since our sets are defined by strict inequalities(< or >)
In interval notation
