Answer: The angles are neither complementary nor supplementary.
Step-by-step explanation:
If the sum of two angles is 180 degrees then we call them as supplementary angles.
If the sum of two angles is 90 degrees then we call them as complementary angles.
The given angles : m∠ABC=138° and m∠DEF=31°
Sum of angles =m∠ABC+ m∠DEF=
which is nor equals to neither
.
Hence, The angles are neither complementary nor supplementary.

Answer:
The relationship between two variables is decreasing and linear.
Step-by-step explanation:
From the given table it is notice that the function passing through the points (1,5), (2,-1), (3,-7) and (4,-13).
Slope of the function between first two points (1,5) and (2,-1) is
Slope of the function between last two points (3,-7) and (4,-13) is
The rate of change or slope of the function is constant.
From the given table it is noticed that the values of y decreased by 6 units as the values of x increased by 1 units.
Since the rate of change constant and negative, therefore the relationship between two variables is decreasing and linear.
