Answer: f(x) = -3/2x -2
Step-by-step explanation:
Slope form of a line is y=mx+b, where b is the y-intercept and m is the slope. We find the y-intercept when we look at when x is 0 which would be -2. The slope is graphing to plots and determining if the slope is positive- going up- or negative- going down. The slope is going down and after using y2 - y1 / x2 - x1, I found the slope was -3/2.

Hey Cassidy.
Our goal is to combine like-terms.
Here are our terms:
3
![\sqrt{10}](https://tex.z-dn.net/?f=%20%5Csqrt%7B10%7D%20)
+ 7
![\sqrt{15}](https://tex.z-dn.net/?f=%20%5Csqrt%7B15%7D%20)
- 6
![\sqrt{10}](https://tex.z-dn.net/?f=%20%5Csqrt%7B10%7D%20)
- 4
![\sqrt{15}](https://tex.z-dn.net/?f=%20%5Csqrt%7B15%7D%20)
Let's combine like-terms.
3
![\sqrt{10}](https://tex.z-dn.net/?f=%20%5Csqrt%7B10%7D%20)
- 6
![\sqrt{10}](https://tex.z-dn.net/?f=%20%5Csqrt%7B10%7D%20)
= -3
![\sqrt{10}](https://tex.z-dn.net/?f=%20%5Csqrt%7B10%7D%20)
7
![\sqrt{15}](https://tex.z-dn.net/?f=%20%5Csqrt%7B15%7D%20)
- 4
![\sqrt{15}](https://tex.z-dn.net/?f=%20%5Csqrt%7B15%7D%20)
= 3
![\sqrt{15}](https://tex.z-dn.net/?f=%20%5Csqrt%7B15%7D%20)
We are left with:
3
![\sqrt{15}](https://tex.z-dn.net/?f=%20%5Csqrt%7B15%7D%20)
- 3
![\sqrt{10}](https://tex.z-dn.net/?f=%20%5Csqrt%7B10%7D%20)
Your answer is B.)
I hope this helps!
Answer:
A = 10.27cm²
Step-by-step explanation:
Let's represent the width as x,
therefore since the length is 4 more than 3 times the width, it can be represent as 3x + 4, Perimeter = 18.4cm
Perimeter of a rectangle = 2(L + B)
![18.4= 2(3x+4+x)\\18.4= 6x+8+2x\\18.4-8=6x+2x\\10.4=8x\\x=\frac{10.4}{8}\\x=1.3](https://tex.z-dn.net/?f=18.4%3D%202%283x%2B4%2Bx%29%5C%5C18.4%3D%206x%2B8%2B2x%5C%5C18.4-8%3D6x%2B2x%5C%5C10.4%3D8x%5C%5Cx%3D%5Cfrac%7B10.4%7D%7B8%7D%5C%5Cx%3D1.3)
width = 1.3cm
Length = 3x + 4 = 3*1.3 + 4 = 7.9cm
Area of a rectangle = length x width
A = 7.9 * 1.3 = 10.27cm²
