Answer:
8
Step-by-step explanation:
- An Equilateral Triangle (3 sides) has 3 Lines of Symmetry
- A Regular Pentagon (5 sides) has 5 Lines of Symmetry
- A Regular Hexagon (6 sides) has 6 Lines of Symmetry
- A Regular Heptagon (7 sides) has 7 Lines of Symmetry
- A Regular Octagon (8 sides) has 8 Lines of Symmetry
Solve for x or y or 1
solving for y
divide both sides by x
y=25/x
not a line because x has t ohave exponent of 1, this one is y=25x^-1
ok, solve for something else
solve for 1
xy/25=1
this doesn't fit into the standard forms of any of the conic sections
if we were to subsitute points we would see it is a hyperbola that is diagonal with the x and y axises as assemtots
it is a hyperbola
I did the work and it's D. i believe

Answer:
<u>First blank:</u> 2. Extrapolation
<u>Second blank:</u> 2. 69
Step-by-step explanation:
Extrapolation should be used because the point (x, y) is further than the points included in the table, that is, the x-coordinate will be greater than 12 when y = $0
Replacing y = 0 into the equation, we get:
0 = -115.9x + 8,007.30
115.9x = 8,007.30
x = 8,007.30/115.9
x = 69
