Answer:
x=4 y=8
Step-by-step explanation:
y=2x
y=12-x
Substituiting y value from first equation into second equation.
2x=12-x
3x=12
x=4
y=2(4)=8
y=12-4=8
Answer:
g(x)=x2−x−6g(x)=x2-x-6
Set x2−x−6x2-x-6 equal to 00.
x2−x−6=0x2-x-6=0
Solve for xx.
Tap for fewer steps...
Factor x2−x−6x2-x-6 using the AC method.
Tap for more steps...
(x−3)(x+2)=0(x-3)(x+2)=0
If any individual factor on the left side of the equation is equal to 00, the entire expression will be equal to 00.
x−3=0x-3=0
x+2=0x+2=0
Set x−3x-3 equal to 00 and solve for xx.
Tap for more steps...
x=3x=3
Set x+2x+2 equal to 00 and solve for xx.
Tap for more steps...
x=−2x=-2
The final solution is all the values that make (x−3)(x+2)=0(x-3)(x+2)=0 true.
x=3,−2
