Answer:
(-5-5x)/(4x+3
Step-by-step explanation:
Replace x with y to get (-3y-5)/(4y+5). Solve for y to get (-5-5x)/(4x+3).
Answer:
The minimum value of y is -7
Step-by-step explanation:
Given: ![y=-1+6\cos(\dfrac{2\pi}{7}(x-5))](https://tex.z-dn.net/?f=y%3D-1%2B6%5Ccos%28%5Cdfrac%7B2%5Cpi%7D%7B7%7D%28x-5%29%29)
We are given a cosine function.
We need to find minimum value of function.
![y=-1+6\cos(\dfrac{2\pi}{7}(x-5))](https://tex.z-dn.net/?f=y%3D-1%2B6%5Ccos%28%5Cdfrac%7B2%5Cpi%7D%7B7%7D%28x-5%29%29)
Here y is depends on cosine function.
y is minimum when cosine is minimum because y is directly proportional to cosine function.
Minimum value of cos x is -1
Therefore, For minium value of y
![\cos(\dfrac{2\pi}{7}(x-5))=-1](https://tex.z-dn.net/?f=%5Ccos%28%5Cdfrac%7B2%5Cpi%7D%7B7%7D%28x-5%29%29%3D-1)
Minimum value of y
![y=-1+6(-1)](https://tex.z-dn.net/?f=y%3D-1%2B6%28-1%29)
![y=-7](https://tex.z-dn.net/?f=y%3D-7)
Hence, The minimum value of y is -7
Answer:
48 degrees
Step-by-step explanation:
y is perpendicular on x axis so it make 90 degree angle
so 42 degree+48 degree=90 degree
