Answer:
Step-by-step explanation:
< 1 = 110
< 2 = 180 - 110 = 70
<5 = 180 - 110 = 70
<6 = <1 = 110
==================
<9 = 103
<13 = 180 - 103 = 77
<10 = <13 = 77
<14 = <9 - 103
====================
<2 = < 4 = 70 Property of l || m
<3 = <1 = 110 Same as above
<7 = <5 = 70 Same as above and vertical angles.
<6 = <8 = 110 Same as above
=====================
<11 = < 9 = 103 Parallel line property
<15 = <13 = 77 Same as above
<12 = <10 = 77 Same as above
<16 = <15 = 103 Parallel line property.
=> 5x + 9 = 4
Adding - 9 on both sides,
=> 5x + 9 - 9 = 4 - 9
=> 5x = - 5
Divide by 5 on both sides,
![= > \frac{5x}{5} = \frac{ - 5}{5}](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20%20%5Cfrac%7B5x%7D%7B5%7D%20%20%3D%20%20%5Cfrac%7B%20-%205%7D%7B5%7D%20)
=> x = - 1
Hence the value of the variable x is - 1
Using the function concept, it is found that this sequence is a function because it passes the vertical line test.
A function relates <u>each value of the input to one value of the output</u>, hence, option b is incorrect.
- On a graph, each value of x(horizontal axis) is mapped to a value of y(vertical axis), hence, a vertical line test can be applied to determine whether the relation is a function.
In this problem:
- For each day, there is only one output, which is her balance, hence, it passes the vertical line test.

Answer:
See below
Step-by-step explanation:
a) 47/100
b) .4777777..... =x
then 10x = 4.77777....
100x = 47.777777 .... now subtract 10x to get
90x = 43
x = 43/90
c) .4747474747...... = x
100x = 47.474747 now subtract x to get
99x = 47
x = 47/99
