<em>the answer to this question is </em><em>31</em><em> </em>
If you were to have (3,2) and find the reflection of the y axis, it would turn y into a negative, making it (3,-2).
<u>9a³ - 37a² - 42a + 20</u> = 9a² + 8a - 2 with a remainder of 30
a - 5
Step-by-step explanation:
¡)
The lowest rank of the class is unknown to us.
Let's say, it's x.
highest marks =2 × lowest rank + 7
=> 87 = 2x + 7 (this is the equation we gotta solve)
=> 87 - 7 = 2x
=> 2x = 80
=> x = 40
And x is the lowest rank of the class, so we got the required answer.
![\boxed{ \mathfrak{lowest \: rank = \red{40}}}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%20%5Cmathfrak%7Blowest%20%5C%3A%20rank%20%3D%20%20%5Cred%7B40%7D%7D%7D)
¡¡)
it can be 17 since the denominators are in increasing order and 17 only fits in.
I'm looking for any other pattern that can be present here.
