Move all the logarithms on the left hand side, and all the constants on the other:
Use the rule of logarithms
To rewrite the equation as
Evaluate 2 to the power of each side:
Multiply both sides by 2x:
Answer:
Table C
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
Find the value of the constant of proportionality in each table
Table A
For ------>
For ------>
This table has different values of k
therefore
the table A does not represent a proportional relationship
Table B
For ------>
For ------>
For ------>
This table has different values of k
therefore
the table B does not represent a proportional relationship
Table C
For ------>
For ------>
For ------>
For ------>
This table has the same value of k
therefore
the table C represent a proportional relationship
Table D
For ------>
For ------>
For ------>
For ------>
This table has different values of k
therefore
the table D does not represent a proportional relationship
