Answer:
y = -1/2 x - 3 1/2
Step-by-step explanation:
points (1, -4) (3,-5)
slope = (y2-y1)/ (x2-x1)
slope = (-5--4)/(3-1)
= (-5+4) /2
=-1/2
point slope form of a line
y-y1 = m(x-x1)
y--4 = -1/2 (x-1)
y+4 = -1/2 (x-1)
if we want slope intercept form
distribute
y+4 = -1/2 x + 1/2
subtract 4 from each side
y+4-4 = -1/2 x + 1/2 -4
y = -1/2 x - 3 1/2
Answers:
- Volume
- Surface area
==========================================
Explanation:
The volume is the amount of stuff that a container can hold on the inside, while the surface area is the amount of stuff that goes on the outside of the container (eg: the amount of paint or wallpaper). In the case of wallpapering a room, we're actually doing the inner walls rather than the outside walls; however, it's the same concept. The surface area only deals with the surface and we want to find out how much area we have to cover. That way we can know how much wallpaper to buy. For problem 1, he needs to know the volume so he can find out how much trash each can would be able to hold. The greater the volume, the larger the bin. For instance a small wastebasket would have a small volume compared to a large waist high heavy duty trash container.
Answer:
The value of v with given slop and points is - 6
Step-by-step explanation:
Given as :
Let x and y be the points of a line
So, x = ( - 3 , - 10 ) And y = ( - 4 , v )
The given slop of line XY is - 4
Now, from slop equation :
Slop = 
Or, - 4 = 
Or, - 4 = 
Or, v + 10 = ( -4 ) × (- 1 )
Or, v + 10 = 4
∴ v = 4 - 10 = - 6
Hence The value of v with given slop and points is - 6 Answer
Answer:
Area = 5/6 * x^2
Step-by-step explanation:
If you are given the base and height of a certain triangle, you will most likely be asked to find the area
The area of any triangle can be found by
Area = base*height * (1/2)
In your case
Area = (5/3)*x*x* (1/2) = 5/6 * x^2
In your case, x should be a known parameter of your triangle, so if you have the value of the height, you should be able to find the area. Or conversely, if you have the area, you can find the length and height of your triangle.
