Answer:
m∠2=9
Step-by-step explanation:
Hello There!
The problem states that the angles are complementary angles
Complementary angles are angles that have measures that add up to equal 90
So given one of the angles we can find the missing angle by subtracting the known angle from 90
90 - 81 = 9
so we can conclude that the measure of angle 2 is 9
Answer: Option A
Step-by-step explanation:
A relation between two variables x and y is considered a function if and only if, for each input value x there is only one output value y.
If for an input value
there are two output values
and
then the relation is not a function.
Therefore, to answer this question, identify the table in which each value of x has only one value of y.
You may notice that the option that meets this requirement is option A
Note that in option B, there are two output values 17 and 16 for x = -4.
So this relationship is not a function.
In option C there are 2 output values for x = -5
In option D there are 2 output values for x = -11
When x = 6.4, y=117, therefore
15*6.4 + b = 117
b = 117 - 96 = 21
Confirm this value by checking (6.6, 120).
15*6.6 + 21 = 120 (Correct)
Answer: b = 21
