Answer:
3. (-3,4) x=-3, y=4
Step-by-step explanation:
1. 3x-y=-13
-y=-13-3x
y=13+3x
2. 4x+2y=-4
4x+2(13+3x)=-4
4x+26+6x=-4
10x+26=-4
10x=-4-26
10x=-30
x=-30/10
x=-3
3. y=13+3x
y=13+3(-3)
y=13-9
y=4

Answer:
x = -2, -5 where -2 is a double root
Step-by-step explanation:
The real roots are the solutions to the cubic equation. You find them by setting each factor equal to 0 and solving for x.


Since -2 appears twice, it is a double root.
