Step-by-step explanation:
Answer:
Part A: No it is not a function
Part B: The equation
Part C: x = 3
Step-by-step explanation:
Part A - The table:
Input (x) Output (y)
6 14
12 15
15 15
25 16
This is a function because it has no repeating inputs values which have alternate outputs. Each input is assigned exactly one output.
Part B - The relation y = 7x - 15 has the value y = 27 when x = 6. You can find it by substituting into the equation.
y = 7(6) -15
y = 42 - 15
y = 27
The value of the relation in the table when x = 6 is y = 14. The equation has the greater value.
Part C: To find when y = 6, set it equal to 6 and solve for x.
6 = 7x - 15
21 = 7x
3 = x
The correct answer is 1/3
I hope this helps you!

Answer:
The first earthquake is 1.9 times greater than the second
Step-by-step explanation:
We need to substract
M1 and M2
M1 - M2 = ㏒(x1/c) - ㏒(x2/c)
by properties of the logarithm
= log(x1) - log(c) - (log(x2) - log(c))
= log(x1) - log(x2)
But, we know that x1 = 80*x2
So,
= log(80) + log(x2) - log(x2)
= 1.903
