Step-by-step explanation:
k that should be right just think of it as you're finding the slope of a line on a graph k
Answer:
The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation.
So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation. And since x + y = 8, you are adding the same value to each side of the first equation.
Answer:
1) y = 5/2x - 3/2
2) y = 2/5x - 4/5
Step-by-step explanation:
1)
(1, 1) and (3, 6)
m = (y2 - y1)/(x2 - x1)
m= (6 - 1)/(3-1)
m= 5/2
m= 5/2
y - y1 = m(x - x1)
y - 1 = 5/2(x - 1)
y - 1 = 5/2x - 5/2
y = 5/2x - 3/2
2)
(2, 0) and (7, 2)
m = (y2 - y1)/(x2 - x1)
m= (2 - 0)/(7 - 2)
m = 2/5
y - y1 = m(x - x1)
y - 0 = 2/5(x - 2)
y = 2/5x - 4/5
Answer: 110 square inches.
Step-by-step explanation:
The volume of a rectangular box would be:
![V=length*width*height](https://tex.z-dn.net/?f=V%3Dlength%2Awidth%2Aheight)
In this case, we know the volume, the length and the height, and we don't know the width, so we're going to isolate it:
![width=\frac{V}{length*height}](https://tex.z-dn.net/?f=width%3D%5Cfrac%7BV%7D%7Blength%2Aheight%7D)
Substituting the data:
![width=\frac{330}{11*3} =10in](https://tex.z-dn.net/?f=width%3D%5Cfrac%7B330%7D%7B11%2A3%7D%20%3D10in)
This width is also the width of the top of the box, so the area of the top would be:
![A=length*width\\A=11*10\\A=110in^{2}](https://tex.z-dn.net/?f=A%3Dlength%2Awidth%5C%5CA%3D11%2A10%5C%5CA%3D110in%5E%7B2%7D)
