Answer:
y=x/2
Step-by-step explanation:
If one line is perpendicular to another, then the product of their slope is -1.
y = –2x+8. This line has a slope of -2. Which means another line must have a slope of 1/2.
By knowing the slope, we then assume this line as x-2y=k. Insert the point in, we find out k=0.
So the equation of this line is x-2y=0, or y=x/2.
A convex figure with three sides is triangle. The sum of the measures of all interior angles of the triangle is 180°.
Let
be interior angles of this triangle. Then
![\alpha+\beta+\gamma=180^{\circ}.](https://tex.z-dn.net/?f=%5Calpha%2B%5Cbeta%2B%5Cgamma%3D180%5E%7B%5Ccirc%7D.)
Find exterior angles of this triangle:
1.
is exterior angle adjacent to the interior angle ![\alpha.](https://tex.z-dn.net/?f=%5Calpha.)
2.
is exterior angle adjacent to the interior angle ![\beta.](https://tex.z-dn.net/?f=%5Cbeta.)
3.
is exterior angle adjacent to the interior angle ![\gamma.](https://tex.z-dn.net/?f=%5Cgamma.)
The sum of the measures of all exterior angles is
![180^{\circ}-\alpha+180^{\circ}-\beta+180^{\circ}-\gamma=540^{\circ}-(\alpha+\beta+\gamma)=540^{\circ}-180^{\circ}=360^{\circ}.](https://tex.z-dn.net/?f=180%5E%7B%5Ccirc%7D-%5Calpha%2B180%5E%7B%5Ccirc%7D-%5Cbeta%2B180%5E%7B%5Ccirc%7D-%5Cgamma%3D540%5E%7B%5Ccirc%7D-%28%5Calpha%2B%5Cbeta%2B%5Cgamma%29%3D540%5E%7B%5Ccirc%7D-180%5E%7B%5Ccirc%7D%3D360%5E%7B%5Ccirc%7D.)

Answer:
The equation is
y = $ 12.35 x
Step-by-step explanation:
Cost of one bag of rocks = $ 12.35
Let there are x bags of rocks, so that the total cost is y.
So, the cost of 1 bag = $ 12.35
cost of x bags = $12.35 x
The total cost is
y = $12.35 x
It is the equation of a straight line which passes from origin and the slope is 12.35.
