Answer:
Both two lines
Step-by-step explanation:
Parallel lines are two lines thar never meet no matter what, and perpendiculare lines do. And these terms usually refer to two lines an dtheir placement so that's what I think.
Answer:
1. -2=-x - 9, 7=-x, -7=x
2. -1=-x - 9, 8=-x, -8=x
3. 0=-x - 9, 9=-x, -9=x
4. 1=-x - 9, 10=-x, -10=x
5. 2=-x - 9, 11=-x, -11=x
This equation is unsolvable.
x^2+8x+16=0
(x+4)^2+9=0
(x+4)^2= -9
anything to the power of whatever has to be greater than -1, it means it can be 0 or more but never a negative number. If it is a negative number, then it is false.
