Answer:
Area = 21/2 = 10.5 area units
Step-by-step explanation:
Two of the points are on the same line (the y-axis) as they both have x-coordinates of 0. This can thus be the base of your triangle.
Two more are on the same line (y= -9) as they both have the same y-coordinate of -9. This can be the height of your triangle.
So you have a base which is between -2 and -9 (7 units) and a height which is between 0 and 3 (3 units) so now just use the equation for area of a triangle
Answer:
![d \: = \frac{s + 6}{b}](https://tex.z-dn.net/?f=d%20%5C%3A%20%20%3D%20%20%5Cfrac%7Bs%20%2B%206%7D%7Bb%7D%20)
Step-by-step explanation:
![s = db - 6](https://tex.z-dn.net/?f=s%20%3D%20db%20-%206)
Isolate d
![s + 6 = db](https://tex.z-dn.net/?f=s%20%2B%206%20%3D%20db)
.
Divide both sides of the equation by b
![\frac{s + 6}{b} = \frac{db}{b}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bs%20%2B%206%7D%7Bb%7D%20%20%3D%20%20%5Cfrac%7Bdb%7D%7Bb%7D%20)
Simplify
![\frac{s + 6}{b} = d \\ d = \frac{s + 6}{b}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bs%20%2B%206%7D%7Bb%7D%20%20%3D%20d%20%5C%5C%20d%20%3D%20%20%5Cfrac%7Bs%20%2B%206%7D%7Bb%7D%20)
Answer:
2790
Step-by-step explanation:
38/100 * 4500 = 1710 get less than eight hours of sleep
4500 - 1710 = 2790 students
Answer:
y=57, x=77
Step-by-step explanation:
The line that creates x-3 is parrelell to the line that makes 74 degrees
You know that x-3=74
When you simplify you get x=77
Now that you know that x-3=74 you can add all the angles to 180 because they are a supplementary angle
74+41+(y+8)=180, then simplify
115+y+8=180, simplify more
123+y=180
y=57
B is the most logical answer
