6 is the height for the parallelogram, <span />
Answer:
A. 2(x + 9) = 8
Step-by-step explanation:
To solve this problem, we proceed as follows:
- We call "x" the number picked up by Amy:
![x](https://tex.z-dn.net/?f=x)
- Amy then adds 9 to this number, so we get:
![x+9](https://tex.z-dn.net/?f=x%2B9)
- Then, we multiply this sum by 2, so we get:
![2(x+9)](https://tex.z-dn.net/?f=2%28x%2B9%29)
- Finally, Amy says that this number is equal to 8:
![2(x+9)=8](https://tex.z-dn.net/?f=2%28x%2B9%29%3D8)
So the correct equation is
A. 2(x + 9) = 8
We can even solve it to find the number. We get:
![2(x+9)=8\\2x+2\cdot 9 = 8\\2x+18=8\\2x+18-18=8-18\\2x=-10\\x=\frac{-10}{2}=-5](https://tex.z-dn.net/?f=2%28x%2B9%29%3D8%5C%5C2x%2B2%5Ccdot%209%20%3D%208%5C%5C2x%2B18%3D8%5C%5C2x%2B18-18%3D8-18%5C%5C2x%3D-10%5C%5Cx%3D%5Cfrac%7B-10%7D%7B2%7D%3D-5)

Step-by-step explanation:
Answer:
A = 51 degrees
Step-by-step explanation:
We can use the law of sines
sin A sin 95
------------ = -----------
7 9
Using cross products
9 sin A = 7 sin 95
Divide each side by 9
sin A = 7/9 sin 95
Take the inverse of each side
sin ^-1 sin A = sin ^-1 ( 7/9 sin 95)
A = 50.78854367
To the nearest degree
A = 51 degrees
It -6 only, because it’s the only value that the function passes through the y axis
