Answer:
Lines. A ray is a line that originates from a point till infinity.
Step-by-step explanation:
A ray is a form of a line, but it has a starting point. It starts from a point, and extends till infinity in a given or required direction.
This property distinguish completely a ray from a line or segment. Lines extends to infinity in both its directions. And a segment is the length of a line between its starting point and end point.
Thus, we can say that rays are special forms or types of lines.
Answer:
12k
Step-by-step explanation:
Answer:
y is -16
Step-by-step explanation:
Fory =3x -1
Substitute x= -5
y=3(-5) -1
3(-5) -1= -16
y= -16
6xy^2 - xy + 8 + 12y is a polynomial of degree 3
Answer:
70.
Step-by-step explanation:
1) to calculate the values of the 'x':
4x+15=x²-13x+85; ⇔ x²-17x+70=0; ⇔
x₁=7; x₂=10;
2) to calculate the required k:
k=x₁*x₂; k=7*10=70.
