The two angles together form a straight angle, i.e. an angle of 180 degrees. This means that
![7x + 2x+27 = 180](https://tex.z-dn.net/?f=%207x%20%2B%202x%2B27%20%3D%20180%20)
Sum like terms:
![9x+27 = 180](https://tex.z-dn.net/?f=%209x%2B27%20%3D%20180%20)
Subtract 27 from both sides:
![9x = 153](https://tex.z-dn.net/?f=%209x%20%3D%20153%20)
Divide both sides by 9:
![x = \dfrac{153}{9} = 17](https://tex.z-dn.net/?f=%20x%20%3D%20%5Cdfrac%7B153%7D%7B9%7D%20%3D%2017%20)
Answer:
36x^6/y^10
Step-by-step explanation:
First evaluate the parentheses, 6x^3 x 6x^3 = 36x^6
y^5 x y^5 = y^10 ; remember m^k x m^r = m^k+r
final answer should be 36x^6/y^10
hope this helps :')
Answer:
a=-5
Step-by-step explanation:
divide both sides by -2: -5=a
a=-5
Answer:
The answer is D. Vertex at (-7,-9).
Step-by-step explanation:
The equation is in vertex form, so you take the opposite of x and the constant stays the same. So, the opposite of 7 is -7 and -9 stays the same.
Slope (y2-y1)/(x2-x1)
(-3-9)/(15-19) = -12/-4 = 3
The slope is 3
