Answer:
The equation of line is:
![77x+4y=340](https://tex.z-dn.net/?f=77x%2B4y%3D340)
Step-by-step explanation:
Given points:
and ![(4,8)](https://tex.z-dn.net/?f=%284%2C8%29)
To find the equation of the line.
Solution:
In order to find the equation of the line we will first find the slope of the line.
The slope of a line passing through points
and
the slope can be given as:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Plugging in the given points to find the slope of the line.
![m=\frac{8-85}{4-0}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B8-85%7D%7B4-0%7D)
![m=\frac{-77}{4}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-77%7D%7B4%7D)
Equation of line can be written in point slope form as:
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
where
is a point on the line.
Using point (4,8)
![y-8=-\frac{77}{4}(x-4)](https://tex.z-dn.net/?f=y-8%3D-%5Cfrac%7B77%7D%7B4%7D%28x-4%29)
Multiplying both sides by 4.
![4(y-8)=4.(-\frac{77}{4})(x-4})](https://tex.z-dn.net/?f=4%28y-8%29%3D4.%28-%5Cfrac%7B77%7D%7B4%7D%29%28x-4%7D%29)
![4(y-8)=-77(x-4)](https://tex.z-dn.net/?f=4%28y-8%29%3D-77%28x-4%29)
Using distribution:
![4y-32=-77x+308](https://tex.z-dn.net/?f=4y-32%3D-77x%2B308)
Subtracting
both sides.
![4y-4y-32=-77x-4y+308](https://tex.z-dn.net/?f=4y-4y-32%3D-77x-4y%2B308)
![-32=-77x-4y+308](https://tex.z-dn.net/?f=-32%3D-77x-4y%2B308)
Subtracting 308 both sides.
![-32-308=-77x-4y+308-308](https://tex.z-dn.net/?f=-32-308%3D-77x-4y%2B308-308)
![-340=-77x-4y](https://tex.z-dn.net/?f=-340%3D-77x-4y)
Multiplying each term with -1.
![340=77x+4y](https://tex.z-dn.net/?f=340%3D77x%2B4y)
Thus, equation of line is:
![77x+4y=340](https://tex.z-dn.net/?f=77x%2B4y%3D340)
Answer:
What do you mean by this?
A) 31%
B) 31%
For the first problem, we know that 25 out of 80 tokens are black. To find the percentage all we have to do is divide 25 by 80, which equal 0.31. To convert this to percentage form, you move the decimal two places to the right, giving you 31%.
And for the second problem you do the same thing. Divide 5 by 16, giving you 0.31. Convert that into percentage, also giving you the percent of 31%.
