Answer:
taking away is subtracting so if you take away 10 from 67 the equation would be 67-10
the answer would be 57
Given the equation of parabola: y = -x² - 2x - 5
y = ax² + bx + c and negative value of 'a' tell us that it is a downward open parabola whose axis of symmetry would be x = k.
where k is the x-coordinate of vertex of given parabola.
Finding the vertex of parabola, x =
So, the axis of symmetry for this parabola is x = -1.
Answer:
the answer is c
Step-by-step explanation:
In geometry, the definition of a triangle is a two-dimensional closed figure with three sides. Aside from this, it is proven that the sum of the angles of a triangle is 180°. This is a triangle's innate property. Therefore, any closed shape with three sides is a triangle and it follows that the sum of the three angles is equal to 180°.
It is logical therefore, that the first step in proving this is by using the definition of a triangle.
