Answer:
x = 180 -56= 124..... linear pair
y= 180 -39 =141 linear pair
Hello!
Mode :

Given observations are :-
22,40,21,18,47,22,19
Now , mode =

The answer is 22 as it appears two times in the given set of observations.
Hope this is clear :)
Have a good day:)
Answer:
Step-by-step explanation:
The domain includes all x values, and here, it is [-2, 4].
Solve first for the solution of the inequalities. This can be done by replacing first the inequalities sign with the equal sign.
x + y = 1
2y = x - 4
The values of x and y from the system of linear equation are 2 and -1. This means that the intersection of the lines should be at point (2, -1).
Substitute 3 to x and determine the value of y from the second inequality.
2y ≥ x - 4
Substituting,
2y ≥ 3 - 4, y ≥ -1/2
Hence, the solution to this item should be the fourth one.
