Answer:
OK so your doing that lemmethink
Answer:
The answer is -48
Step-by-step explanation:
First step is to follow PEMDAS
So we start solving whatever is in the ( )
4^2 is in the ( ) 4^2 = 16 then we multiply
-3 * 16 which is -48
-
So the slope is (y2-y1)/(x2-x1)
(8-4)/(2-1)=
4/1 =
4
Aka. For every 1 week, the number of pictures taken increases by 4.
So it is 4 * w
Check:
4*w = total number of pictures
4*1 = 4
4*2 = 8
4*3 = 12
4*4 = 16
All match the table.

Answer: ![\bold{x^2-\dfrac{181}{13}xy+12y^2=0}](https://tex.z-dn.net/?f=%5Cbold%7Bx%5E2-%5Cdfrac%7B181%7D%7B13%7Dxy%2B12y%5E2%3D0%7D)
<u>Step-by-step explanation:</u>
![\tan \theta =\dfrac{y}{x}\quad \longrightarrow \theta=\tan ^{-1}\bigg(\dfrac{y}{x}\bigg)](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%20%3D%5Cdfrac%7By%7D%7Bx%7D%5Cquad%20%5Clongrightarrow%20%5Ctheta%3D%5Ctan%20%5E%7B-1%7D%5Cbigg%28%5Cdfrac%7By%7D%7Bx%7D%5Cbigg%29)
![\text{Given:}\quad \theta =\tan^{-1}\bigg(\dfrac{1}{13}\bigg)\quad \longrightarrow x=13,y=1](https://tex.z-dn.net/?f=%5Ctext%7BGiven%3A%7D%5Cquad%20%5Ctheta%20%3D%5Ctan%5E%7B-1%7D%5Cbigg%28%5Cdfrac%7B1%7D%7B13%7D%5Cbigg%29%5Cquad%20%5Clongrightarrow%20x%3D13%2Cy%3D1)
Insert x = 13 and y = 1:
x² + 2hxy + 12y² = 0
(13)² + 2(13)(1) + 12(1)² = 0
169 + 26h + 12 = 0
26h + 181 = 0
26h = -181
![h=-\dfrac{181}{26}](https://tex.z-dn.net/?f=h%3D-%5Cdfrac%7B181%7D%7B26%7D)
