Name the property of equality that justifies the statement: rs = rs
2 answers:
Answer:
reflexive property
Step-by-step explanation:
a. reflexive property
For example a=a . both sides should be equal
represents reflexive property
b. symmetric property
For example : if a=b+c then b+c=a
does not represents symmetric property
c. transitive property
For example , if c=b and b=4 then c=4
does not represents transitive property
d. substitution property
for example if x=12+y and y =2
then x= 12+2=14
does not represents substitution property

First of all, a positive average rate of change means that the function is increasing, so the answer can only be A->B or B->C.
The average rate of change is defined as
i.e. as the ratio between the vertical and horizontal gain.
In order to go from point A to point B, you gain 1 unit horizontally and 5 units vertically. So, the average rate of change is 5/1=5.
In order to go from point B to point C, you gain 1 unit horizontally and 3 units vertically. So, the average rate of change is 3/1=3.
