Answer:
A
Step-by-step explanation:
(2m-n) is a factor of 4(2m-n)
A) The result of adding the two equations is
.. (2.5y +3x) +(5x -2.5y) = (27) +(5)
.. 8x = 32 . . . . . . . . . . . . . . . . . . . . . . . your 2nd selection
b) The solution to the system is (4, 6), your 4th selection.
.. This is the only choice with x=4, the solution to part (a).
Answer:
d
Step-by-step explanation:
just took the test
3x - 4y = 11
For (3, -8): 3(3) - 4(-8) = 9 + 32 = 41 ≠ 11.
For (4, 4): 3(4) - 4(4) = 12 - 16 = -4 ≠ 11
