Answer 1

Step-by-step explanation:

Step-by-step explanation:Is  ?

Step-by-step explanation:Is  ?Work with the same base: is  ? --> is  ? --> is ? is ?

Step-by-step explanation:Is  ?Work with the same base: is  ? --> is  ? --> is ? is ?(1) x - y = 9. Not sufficient.

Step-by-step explanation:Is  ?Work with the same base: is  ? --> is  ? --> is ? is ?(1) x - y = 9. Not sufficient.(2) y/x = 1/4 --> . Not sufficient.

Step-by-step explanation:Is  ?Work with the same base: is  ? --> is  ? --> is ? is ?(1) x - y = 9. Not sufficient.(2) y/x = 1/4 --> . Not sufficient.(1)+(2) We have two distinct linear equation with two unknowns ( and ), hence we can solve for both of them and get whether  is true. Sufficient
