Step-by-step explanation:
Answer:
I'm not really,
sure but I think non linear
Step-by-step explanation:
sorry if I'm wrong
Discriminant b^2-4ac = (-9)^2 - 4*2*9 = 9
so there are 2 roots
because of the -9x and 9 they will both be positive
Answer:
y= 4 , x= -1
Step-by-step explanation:
3x-9y= -39
-3x-7y= -25
-16y= -64
y= -64/-16
y= 4
substitute y into any equation
3x -9(4) = -39
3x-36= -39
3x= -39+36
3x= -3
x= -3/3
x= -1
