In attempting to solve the system of in equality y =3x - 2 and x - 2y = 4, john graphed the two equations on his graphing calculator. because he saw only one line, john wrote that the answer to the system is the empty set. is he correct?

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
