Answer:
Page number 74
Step-by-step explanation:
Let
x ---> the number of days
y ---> the number of pages read
we know that
The linear equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
we have
<em>Anne</em>
The slope is equal to

The y-intercept is equal to

substitute
----> equation A
<em>Willow</em>
The slope is equal to

The y-intercept is equal to

substitute
----> equation B
equate equation A and equation B

solve for x

Find the value of y
substitute the value of x in equation A or equation B
equation A

equation B

Answer:

Step-by-step explanation:
we know that
The Euler's formula state that: In a polyhedron, the number of vertices, minus the number of edges, plus the number of faces, is equal to two

in this problem we have

substitute the given values

solve for V
Combine like terms left side

Adds 6 both sides


Period For Interest = 9 months
Period taken = 54 months
Investment = 2000
Quarters for payment = 54 ÷ 9
=6 periods
2000×2 = 4000
4000×2 = 8000
8000×2 = 16000
16000×2 = 32000
32000×2 = 64000
64000×2 = 128000
Answer = 128000
