This is a parabola which has vertex at the origin and opens upwards.
general form is x^2 = 4ay where a is the focus
the focus is the same distance from the vertex as the directrix So it is at the point (0, 6)
required equation is x^2 = 4*6 y
or y = (1/24) x^2
Answer:
The answer to your question is: -9y³ - 3y² + 5y - 9
Step-by-step explanation:
( y² - 3y³ - 2 + 5y ) - (7 + 8y² - 4y² + 6y³)
y² - 3y³ - 2 + 5y - 7 - 8y² + 4y² - 6y³
Like terms -3y³ - 6y³ + y² - 8y² + 4y² + 5y - 2 - 7
-9y³ - 3y² + 5y - 9
Answer: Therefore, the age of my sister is 13 years.
