Answer:
Second table.
Step-by-step explanation:
A function has an additive rate of change if there is a constant difference between any two consecutive input and output values.
The additive rate of change is determined using the slope formula,

From the first table we can observe a constant difference of -6 among the y-values and a constant difference of 2 among the x-values.

For the second table there is a constant difference of 3 among the y-values and a constant difference of 1 among the x-values.
The additive rate of change of this table is

Therefore the second table has an additive rate of change of 3.
Answer:

Step-by-step explanation:
Answer:
transposition method
Step-by-step explanation:
it helps to find that value of y
Harmonic mean between two positive numbers x and y, The simplified formula is
I.e. you need to double the product of x and y then divide it by the sum of x and y...~
