The answer for the exercise shown above is the first option, the option A, which is shown below: A. Exponential function.
In a geometric sequence, the ratio of any two consecutive numbers that form the sequence is equal. In other words, they have common ratio.
Answer:
D
Step-by-step explanation:
given the 2 equations
x + 2y = 27 → (1)
2x + 3y = 46 → (2)
Rearrange (1) expressing x in terms of y by subtracting 2y from both sides
x = 27 - 2y ← substitute into (2)
2(27 - 2y) + 3y = 46
54 - 4y + 3y = 46
54 - y = 46 ( subtract 54 from both sides )
- y = - 8 ( multiply both sides by - 1 )
y = 8 → D
Answer: 8
Step-by-step explanation: four plus four equals eight
If they sold 89 calendars over 4 weeks, the 'equation' would look like (x = average calendars sold over 4 weeks):
![x = \frac{89}{4}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B89%7D%7B4%7D%20)
If you solve it, you get:
![22 \frac{1}{4}](https://tex.z-dn.net/?f=22%20%5Cfrac%7B1%7D%7B4%7D%20)
Which is equal to
22.25. Hope this helps!
