So the first four terms of the sequence are
2, 6, 10, 14
Given:
Per month fee = $55
One-time recital fee = $165
The equation represents the $495 total cost that Barbara paid to Dance Unlimited.
![495=165+55m](https://tex.z-dn.net/?f=495%3D165%2B55m)
To find:
We need to find the number of month Barbara receive dance lessons from Dance Unlimited.
Solution:
We have,
![495=165+55m](https://tex.z-dn.net/?f=495%3D165%2B55m)
Here, m is number of months. We need to isolate m.
Subtract 165 from both sides.
![495-165=55m](https://tex.z-dn.net/?f=495-165%3D55m)
![330=55m](https://tex.z-dn.net/?f=330%3D55m)
Divide both sides by 55.
![\dfrac{330}{55}=m](https://tex.z-dn.net/?f=%5Cdfrac%7B330%7D%7B55%7D%3Dm)
![6=m](https://tex.z-dn.net/?f=6%3Dm)
The value of m is 6. So, the required number of month Barbara receive dance lessons from Dance Unlimited is 6.
The answer is B-40.
It is an acute angle so it can not be 155 but the angle does not look like it is close to being 90 degrees so the answer has to be 40!
Hope this helps(can I get brainliest)
All of these have no x-intercepts, since x-intercepts require y to be 0. Their y-intercepts are:
(0, 4)
(0, -18)
(0, 16)
(0, -7)
respectively.
Answer:
See below
Step-by-step explanation:
y = x^2 (x + 4) - 25(x + 4)
y = (x + 4)(x^2 - 25)
y = (x + 4)(x + 5)(x - 5)
- x - 5 is a yes
- x + 2 is a no
- x - 4 is a no
