Answer:
False
True
False
False
Step-by-step explanation:
1. We have to get the sum as follows :
= 
= 
= 
= 
So, this is false.
2. We have to get the sum as follows :
= 
= 
= 
= 
So, this is true.
3. We have to get the difference as follows :
= 
= 
= 
= 
So, this is false.
4. We have to get the difference as follows :
= 
= 
= 
= 
So, this is also false. (Answer)

Answer:
We can use slope intercept form to get the points needed. Y= -7+1/3x The points are (0,-7) and (3,-6)
Step-by-step explanation:
Subtract 2x from the left side and place it over to the right side with the 42. Now we have -6y= 42-2x. From here we divide by -6 and we get y= -7+1/3x. We know that are slope is 1/3 which the one is the rise and the 3 is the run. We also know that our y intercept is -7. We plot the points at (0,-7) and (3,-6)

Answer:
16,25,30,49
25+30=55
55÷2=27.5
Step-by-step explanation:
median means the middle value of any set of data so first arrange the data into ascending order.
16, 25, 30, 49
the data is even so we take both the middle value , add it and divide it with 2
25+30=55
55÷2=27.5
