Multiply 2nd equqation by -1 and add to first
5x+4y=22
<u>-3x-4y=-10 +</u>
2x+0y=12
2x=12
divide by 2
x=6
sub back
3x+4y=10
3(6)+4y=10
18+4y=10
minus 18 both sides
4y=-8
divide by 4
y=-2
(x,y)
(6,-2) is solution
The domain is all of the x values
(x^2-3x+2)-1(3x^2-5x-1)=
x^2-3x+2-3x^2+5x+1=
x^2-3x^2-3x+5x+2+1=
-2x^2+2x+3
Answer:
-10
Step-by-step explanation:
