Answer:
3x - y = -1
Step-by-step explanation:
Standard form of equation is Ax + By = C
y - y1 = m (x -x1)
y - 7 = 3 (x - 2)
y - 7 = 3x - 6
3x - y = -7 +6
3x - y = -1
Given:

To find:
The value of
.
Solution:
We need to find the value of:

It can be written as


By using the property of logarithm, we get
![[\because \log \dfrac{a}{b}=\log a-\log b]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog%20%5Cdfrac%7Ba%7D%7Bb%7D%3D%5Clog%20a-%5Clog%20b%5D)

On substituting the given values, we get


Therefore, the values of
is -0.222.
6 to the 2nd power divided by 2(3)+4 = 58
