Answer:
I think this is the correct solution
The U and inverted U symbols, ∪ and ∩, are mathematical symbols used to denote union or intersection, respectively. For example, when a rational algebraic equation is graphed, there may be some points where the equation is undefined. Visually, we see it as breaks or discontinuities. We use the ∪ symbol to express union. For example, {-∞,2)∪(4,+∞). That means that the graph passes at all x values except x=3.
The ∩ symbol is used for intersection of two lines, for instance. When equation A and equation B are graphed, they can intersect at points (x,y). It is therefore expressed as: A∩B = (x,y).
Answer:
-9/8
Step-by-step explanation:
Slope m = (y2-y1)/(x2-x1)
using (1,1) and (10,9)
m = (9 - 1)/(10 - 1)
m = (8)/(9)
m = 8/9
slope of line g is 8/9
Perpendicular lines have slopes that are negative reciprocals of one another
so slope of h is -9/8
