Answer:
Step-by-step explanation:
Vertical angles are congruent.
8x = 2x +30
6x = 30 . . . . . . subtract 2x
x = 5 . . . . . . . . divide by 6
__
60y -40 = 40y +20
20y = 60 . . . . add 40-40y
y = 3 . . . . . . . .divide by 20
_____
<em>Check</em>
The 'x' angles are 8x° = 8·5° = 40°.
The 'y' angles are (40y+20)° = (40·3+20)° = 140°.
The angles are supplementary, as they are supposed to be.
Answer:
x = -11
Step-by-step explanation:
To find the zero of this function, factor the equation:
g(x) = ![x^{2} +22x+121](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B22x%2B121)
g(x) = (x + 11) (x + 11)
g(x) = ![(x+11)^{2}](https://tex.z-dn.net/?f=%28x%2B11%29%5E%7B2%7D)
The zeros of a function are the values of x that will make g(x) equal 0. So, the zero of this function is -11, because -11 + 11 = 0. So, x = -11.
Answer:
A) 2^12
Step-by-step explanation:
3x - y = 12
3(5) - 3 = 12
15 - 3 = 12
12 = 12
![\frac{8^x}{2^y}](https://tex.z-dn.net/?f=%5Cfrac%7B8%5Ex%7D%7B2%5Ey%7D)
![\frac{8^5}{2^3}](https://tex.z-dn.net/?f=%5Cfrac%7B8%5E5%7D%7B2%5E3%7D)
![\frac{32768}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B32768%7D%7B8%7D)
