Answer:
-1 and 3
Step-by-step explanation:
The x intercepts are where the graph crosses the x axis.
Looking at the graph it crosses at two points
x = -1 and x=3
A) .05n + .10d + .25 q = 10.30
B) d +2 = q
C) n = 3q
Substituting equations B and C into A
A) .05*3q + .10(q-2) + .25 q = 10.30
A) .15q + .1q -.2 + .25q = 10.30
A) .50q = 10.50
21 quarters
C) n = 3q
C) n = 3*21
63 nickels
B) d +2 = q
d + 2 = 21

A priori means as things were in the beginning or at the start.
a posteriori means as things are after any event.
We can find x only if we know that the figure is a REGULAR octagon, i.e. an octagon with all sides equal, and all interior angles equal.
We will ASSUME that the figure is a regular octagon.
For a regular polygon, the central angle subtended by each side is equal.
The central angle is 360 degrees.
So the central angle subtended by a single side euqals
a=360 degrees / 8 sides = 45 degrees / side
Since x is the total angle subtended by three sides, so
x=3*45=135 °
9/10 + 7/100
find the common denominator for 9/10 which is 100
multiply by 10 for 9/10
(9)(10)=90
(10)(10)=100
90/100+7/100
Answer:
97/100
