Answer:
(x + 12)(x - 3)
Step-by-step explanation:
![{x}^{2} + 9x = 36 \\ {x}^{2} + 9x - 36 = 0 \\ {x}^{2} + 12x - 3x - 36 = 0 \\ x(x + 12) - 3(x + 12) = 0 \\ (x + 12)(x - 3) = 0](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%2B%209x%20%3D%2036%20%5C%5C%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%209x%20-%2036%20%3D%200%20%5C%5C%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%2012x%20-%203x%20-%2036%20%3D%200%20%5C%5C%20x%28x%20%2B%2012%29%20-%203%28x%20%2B%2012%29%20%3D%200%20%5C%5C%20%28x%20%2B%2012%29%28x%20-%203%29%20%3D%200)
Answer: You need to show the number line in order to get an answer.
Answer: ![\bold{A)\quad y=5sin\bigg(\dfrac{6}{5}x-\pi\bigg)-4}](https://tex.z-dn.net/?f=%5Cbold%7BA%29%5Cquad%20y%3D5sin%5Cbigg%28%5Cdfrac%7B6%7D%7B5%7Dx-%5Cpi%5Cbigg%29-4%7D)
<u>Step-by-step explanation:</u>
The general form of a sin/cos function is: y = A sin/cos (Bx-C) + D where the period (P) = 2π ÷ B
In the given function,
→ ![P=2\pi \cdot \dfrac{5}{6}=\dfrac{10\pi}{3}](https://tex.z-dn.net/?f=P%3D2%5Cpi%20%5Ccdot%20%5Cdfrac%7B5%7D%7B6%7D%3D%5Cdfrac%7B10%5Cpi%7D%7B3%7D)
Half of that period is: ![\dfrac{1}{2}\cdot \dfrac{10\pi}{3}=\large\boxed{\dfrac{5\pi}{3}}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D%5Ccdot%20%5Cdfrac%7B10%5Cpi%7D%7B3%7D%3D%5Clarge%5Cboxed%7B%5Cdfrac%7B5%5Cpi%7D%7B3%7D%7D)
Calculate the period for each of the options to find a match:
