The basic form of linear function is
y=ax+b
For finding the slope, use the slope formula.
(4-2)/(-2+1)= 2/-1=-2
We first found a which is -2.
Then insert any point to find the value of b. In this case, I will insert (1,-2).
-2=-2+b
b=-2+2=0
The linear graph is y=-2x
Answer:
![-\frac{9}{r^4}](https://tex.z-dn.net/?f=-%5Cfrac%7B9%7D%7Br%5E4%7D)
Step-by-step explanation:
Using Power rule
![\frac{d}{dr} (r^n)=nr^{n-1}\\-\frac{9}{r^4}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7Bdr%7D%20%28r%5En%29%3Dnr%5E%7Bn-1%7D%5C%5C-%5Cfrac%7B9%7D%7Br%5E4%7D)
Answer:
5/y^3
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
You can let y for the inverse
Like
X =5y - 11
Then you will get
X+11=5y
Then x+11/5=y
Answer:
D
Step-by-step explanation:
The surface area of the rectangular prism is the sum of all the 6 faces.
- There are 2 faces with length 3 ft and width 3.4 feet. Hence,
Area = 2 (3*3.4) = 20.4
- There are 2 faces with length 3 ft and width 4.1 ft. Hence,
Area = 2 (3*4.1) = 24.6
- There are 2 faces with length 3.4 ft and width 4.1 ft. Hence,
Area = 2 (3.4*4.1) = 27.88
Thus, Surface Area = 20.4 + 24.6 + 27.88 = 72.88 ft ^2
