Answer:
17: A,C,B 18: C,A,B 19: A,C,B 20:A,C,B
Step-by-step explanation:
Slope(rate of change) can be found by dividing the change in y over the change in x. For example, #17 table, the change in y is (1-0)=1 and the change in x is (6-3)=3. Now, divide the to to get 1/3. Once you have all the rates of change you can list them in order.
Answer:
C. 
Step-by-step explanation:
We have been given a triangle. We are asked to find the measure of angle Z using Law of cosines.
Law of cosines:
, where, a, b and c are sides opposite to angles A, B and C respectively.
Upon substituting our given values in law of cosines, we will get:








Now, we will use inverse cosine or arc-cos to solve for angle Z as:



Therefore, the measure of angle Z is approximately 51 degrees.
Answer:
-13 < 16
Step-by-step explanation:
(4 is x, -5 is y)
-5 - 8 < 4(4)
-13 < 16
It is true and is a solution
