The answer is D and E

Step-by-step explanation:

- D is not a function because x in (x,y) coordinate sets, 1 is being repeated over and in this case 1 is repeated 4 times.

- E is not a function because x in (x,y) coordinate sets, 6 has been repeated 2 times; (6,2), and (6, -1).

Solve using substitution, 5x+y=9 10x-7y=-18

BARSIC [14]

Answer:

See below

Step-by-step explanation:

5x + y = 9 re-arrange to y = 9-5x

use this value of 'y' in the second equation:

10x - 7(9-5x) = - 18

solve for x = 1

sub in this value of 'x' into one of the equations to compute 'y'

5 (1) + y = 9

y = 4
