Since we are asked for tge graph that represent the total cost for the x numbers of lesson, it will be helpful to illustrate it first this way
for each lesson it will cost $30 dollars
1 lesson $30
2 lessons $60
3 lessons $90
4 lessons $120
5 lessons $150
So from this set of numbers , it is apparent that the grqph in letter c represents the total costs for x numbers of lessonsseethati
<span>x^2-15=34
</span><span>x^2 = 34 + 15
</span><span>x^2 = 19
x = + 7 and x = -7
answer is
</span>x = + 7 and x = -7
Answer:
Step-by-step explanation:
The payment for sessions makes a series
- 5 dimes, 5*5 = 25 dimes, 25*5 = 125 dimes, ...
This series is GP with the first term of 5 and common ratio of 5.
The nth term would be
Use the equation above and find the 7th term
