End point - points on either end of a line segment or on one end of a ray.
Ray - A part of a line, with one endpoint, that continues without end in one direction
Line - a line of points that extends infinitely in two directions
Collinear - points that lie on the same line
Midpoint - A point that divides a segment into two congruent segments
Plane - A flat surface on which a straight line joining any two points would wholly lie.
3 dimensions - height, width, and depth
Answer:
(x - 9)(x + 2)
Step-by-step explanation:
x² - 7x - 18
x² + 2x - 9x - 18
x(x + 2) - 9(x + 2)
(x - 9)(x + 2)
Answer:
B = 
A
Step-by-step explanation:
Given that B varies directly as A then the equation relating them is
B = kA ← k is the constant of variation
To find k use the condition A = 90 and B = 40, then
k = 
= 
=
B = A ← equation of variation
