Answer:
![x = 9](https://tex.z-dn.net/?f=x%20%3D%209)
![y = 17](https://tex.z-dn.net/?f=y%20%3D%2017)
Step-by-step explanation:
This is a cyclic quadralterial so opposite angles are supplementary.
The x variables add up to 180 so
![11x + 8 + 8x + 1 = 180](https://tex.z-dn.net/?f=11x%20%2B%208%20%2B%208x%20%2B%201%20%3D%20180)
![19x + 9 = 180](https://tex.z-dn.net/?f=19x%20%2B%209%20%3D%20180)
![19x = 171](https://tex.z-dn.net/?f=19x%20%3D%20171)
![x = 9](https://tex.z-dn.net/?f=x%20%3D%209)
The y variables add up to 180.
![6y - 4 + 5y - 3 = 180](https://tex.z-dn.net/?f=6y%20-%204%20%2B%205y%20-%203%20%3D%20180)
![11y - 7 = 180](https://tex.z-dn.net/?f=11y%20-%207%20%3D%20180)
![11y = 187](https://tex.z-dn.net/?f=11y%20%3D%20187)
![y = 17](https://tex.z-dn.net/?f=y%20%3D%2017)
Answer:
Real roots: -4, 1
Complex roots: 2-5i, 2+5i
Step-by-step explanation:
(x²+3x-4)(x²-4x+29)
x²+3x-4=x²+4x-x-4=x(x+4)-(x+4)=(x-1)(x+4)
x²-4x+29 does not have real roots, since delta=16-4×29=-100<0.
However it has complex roots:
(4+/-10i)/2=2+/-5i
So the real roots are: -4 and 1
Complex roots: 2-5i, 2+5i
Answer:
The Largest Number is 27.
Step-by-step explanation:
Range = Largest Number - Smallest Number
18 = Largest Number - 9
Rearrange the formula to find the Largest Number:
Largest Number = Range + Smallest Number
Largest Number = 18 + 9
Largest Number = 27
You can check this by putting it into the original formula:
Range = Largest Number - Smallest Number
18 = 27 - 9
