<span>2/5 is close to 1/2, and it is easy to find 1/2 of 7 mentally. Half of 7 is 3.5, so Martin gave away about 3.5 pounds.</span>
Let m = slope
Use the point-slope formula.
y - y1 = m(x - x1)
Let y1 = 3
Let x1 = 2
y - 3 = 1(x - 2)
Solve for y.
y - 3 = x - 2
y = x - 2 + 3
y = x + 1
Done!
Answer:
consistent and dependent
Step-by-step explanation:
because are the same equation
k(y)=k(3x+2)
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.
