Answer:
D. (-∞,4]
Step-by-step explanation:
The range is the y values
The lowest y values is negative infinity
The highest y values is 4
( - inf, 4]
We use the parentheses since we cannot get to negative infinity, the bracket since we reach 4
we know that
meter is equal to
centimeters
Step ![1](https://tex.z-dn.net/?f=%201%20)
<u>convert all measurements to centimeters</u>
<u>case 1) </u>![0.81\ m](https://tex.z-dn.net/?f=%200.81%5C%20m)
![0.81\ m = 0.81*100= 81\ cm](https://tex.z-dn.net/?f=%200.81%5C%20m%20%3D%200.81%2A100%3D%2081%5C%20cm%20)
<u>case 2) </u>![1.08\ m](https://tex.z-dn.net/?f=%201.08%5C%20m)
![1.08\ m = 1.08*100= 108\ cm](https://tex.z-dn.net/?f=%201.08%5C%20m%20%3D%201.08%2A100%3D%20108%5C%20cm%20)
<u>case 3) </u>![0.8\ m](https://tex.z-dn.net/?f=%200.8%5C%20m)
![0.8\ m = 0.8*100= 80\ cm](https://tex.z-dn.net/?f=%200.8%5C%20m%20%3D%200.8%2A100%3D%2080%5C%20cm%20)
<u>case 4) </u>![180\ cm](https://tex.z-dn.net/?f=%20180%5C%20cm)
<u>case 5) </u>![18\ cm](https://tex.z-dn.net/?f=%2018%5C%20cm)
Step ![2](https://tex.z-dn.net/?f=%202%20)
<u>Compare the values</u>
we have
![[81,108,80,180,18]](https://tex.z-dn.net/?f=%20%5B81%2C108%2C80%2C180%2C18%5D%20)
the shortest length is ![18](https://tex.z-dn.net/?f=%2018%20)
the longest length is ![180](https://tex.z-dn.net/?f=%20180%20)
Step ![3](https://tex.z-dn.net/?f=%203%20)
<u>Subtract the shortest length from the longest</u>
![180\ cm-18\ cm=162\ cm](https://tex.z-dn.net/?f=%20180%5C%20cm-18%5C%20cm%3D162%5C%20cm%20)
therefore
<u>the answer is</u>
![162\ cm](https://tex.z-dn.net/?f=%20162%5C%20cm)
2 / 10 = 0.2
0.2 as a percent is 20%
Your answer is 20%
4 - 8x = -1 + 1 - 9x + 8
Combine like terms.
4 - 8x = -9x + 8
Add 9x to both sides.
4 + x = 8
Subtract 4 from both sides.
x = 4
The x-intercept is equal to 4.
