Answer:
The axis of symmetry is
Step-by-step explanation:
we know that
In a vertical parabola, the axis of symmetry is equal to the x-coordinate of the vertex
In this problem we have a vertical parabola open upward
The x-coordinate of the vertex is equal to the midpoint between the zeros of the parabola
so
therefore
The axis of symmetry is
Answer:
Step-by-step explanation
nose como se halcjajajajajjje
(3x + 8) + x > 3x - 12
3x + x + 8 > 3x - 12
4x + 8 > 3x - 12
- 3x - 3x
x + 8 > -12
- 8 - 8
x > -20
Solution Set: (-∞, -20)
