I think the answer is C, but I'm not sure.
Answer:
x = 17
Step-by-step explanation:
In order to make any sense of this problem, we must assume the lines that look parallel <em>are</em> parallel. With that assumption, the two marked angles are supplementary:
61° +7x° = 180°
7x = 119 . . . . . . . subtract 61°, divide by °
x = 17 . . . . . . . . divide by 7
Answer:
<h3>Therefore the sum if the series is 15.98!</h3>
The common ratio is 1/2 or 0.5 . If you multiply the current term by the the common ratio the the output will be the next term.
8⋅1/2=4
4⋅1/2=2
2⋅1/2=1 etc ...
because the absolute value of r is less than 1 we can use the following formula.
a/1−r where a is the first term and r is the common ratio
In our problem
a=8 and r=0.5
Substitute
8/1−0.5=8/0.5=16
The sum of this infinite geometric series is 16.
Also, another formula you can use that is guaranteed to work every time, no matter what, is:
Sn=a(r^n−1/r−1)
All the variables work the same way as above, and "n" is the number of terms in the series. So, say you wanted to find the sum of the first 10 terms and were to substitute everything in:
S10=8(0.5^10−1/0.5−1)
S10=15.984375
Therefore the sum if the series is 15.98!

Equations:
y = 20x
y = 20x + 10
y = 20x - 15
The second and third graphs are related to the first graph by having parallel slope, due to the increase in cost total is $20/month.
