Becouse k and n are 'neighbours' so their sum are 180
so k=180-42=138
Answer:

Step-by-step explanation:
Since this sequence starts with -5 and decreases by 2 with each term, its rule would be:

Answer:
1 is allowed on the elevator.
2 is allowed on the elevator.
3 is allowed on the elevator.
4 is not allowed on the elevator.
5 is allowed on the elevator.
Step-by-step explanation:
If the maximum weight capacity of the elevator is 750 pounds, then that means every weight that is 750 pounds or less is allowed on the elevator.
1 is allowed because 700lbs is lower than 750lbs, therefore it is safe.
2 is allowed for the same reason, 620lbs is lower than 750lbs.
etc, etc.
So that's all you need to look for :)
Answer: First Option
The slope is −0.4. Starting at 3.8, the GPA will decrease by 0.4 for every text sent in class.
Step-by-step explanation:
The equation of a line has the following form

Where m is the slope of the line and b is the intercept with the axis of the y
In this case, the equation is:

Observe that

So if x represents the number of texts sent during classes, this means that 
When x increases by one unit then y decreases -0.4. For example when
then 
Then the greatest value it can take the GPA is 3.8. Therefore we can say that the function starts at y = 3.8.
The answer is the first option
